Storm Gate Defenders - Game Design Guide

# Storm Gate Defenders ## Theme You are the keeper of a Storm Gate - an ancient portal that channels wild elemental energy through the Ley Lines of a shattered world. Creatures of corruption are drawn to the Gate's power, seeking to infect it. Your role is to place elemental Conduits along the Ley Lines to redirect, transform, and destroy the corruption before it reaches the Gate. The theme is stormy, electrical, and dramatic - with lightning, crackling energy, and the constant threat of overwhelming darkness. ## Visual Game World The Canvas shows a top-down view of the Storm Gate at the center, pulsing with electrical energy. Ley Lines (gluing pathways) radiate outward from the gate like lightning bolts frozen in time - jagged, branching paths that enemies follow toward the center. The background is dark and stormy with animated rain particles and occasional lightning flashes illuminating the battlefield. Enemies (corruption creatures) spawn from the edges and travel along the Ley Lines toward the Gate. Conduits (your towers) crackle with elemental effects as they fire. When enemies die, they burst into energy particles that flow along the Ley Lines back toward your Gate, visibly transferring their power to you. ## Player Interaction The player interacts directly with the Canvas through spatial decisions: 1. **Click on Ley Line junctions** to place Conduits - these are specific intersection points where you can build 2. **Click on placed Conduits** to select them, then click upgrade options or drag to reposition them (with cost) 3. **Click on the Storm Gate** to activate Overload mode - a powerful AOE attack that consumes stored energy 4. **Click on approaching enemies** to trigger targeted lightning strikes (manual skill shot with cooldown) 5. **Drag between adjacent Conduits** to create Link connections - enemies crossing a linked path take bonus damage ## Entity Types ### Conduit (Basic Tower) - **Sprite**: ProceduralSprite circle with glow effect, colored by element type (blue/air, orange/fire, green/earth, purple/void) - **Appearance**: Glowing orb on a stone base, with electrical arcs reaching toward nearby Ley Lines - **Behavior**: Fires elemental projectiles at enemies in range along Ley Lines - **Interaction**: Player clicks to place on junction points, click to upgrade, drag to reposition for strategic coverage ### Corruption Spawn (Basic Enemy) - **Sprite**: Slime with dark coloration and red glow variant - **Appearance**: Dark blob leaving a trail of corruption, pulsing with sickly red energy - **Behavior**: Moves steadily along Ley Lines toward the Storm Gate, speeding up as it takes damage (desperation) - **Interaction**: Target of player abilities and Conduit attacks, drops visible energy particles on death ### Storm Wraith (Fast Enemy) - **Sprite**: Ghost with lightning color variant - **Appearance**: Translucent, crackling figure that moves in jagged bursts rather than smoothly - **Behavior**: Teleports short distances forward periodically, making range-based towers less effective - **Interaction**: Requires predictive placement and timing from player ### Corruption Titan (Boss Enemy) - **Sprite**: Knight with dark coloration and larger scale - **Appearance**: Massive armored figure with glowing corruption veins, slowly plowing forward - **Behavior**: Absorbs significant damage, spawns smaller Corruption Spawns when hit - **Interaction**: Requires concentrated fire from multiple Conduits, high priority target for player abilities ### Energy Orb (Resource Entity) - **Sprite**: ProceduralSprite diamond with bright yellow/white glow - **Appearance**: Small glowing particles spawned from enemy deaths, traveling along Ley Lines to the Gate - **Behavior**: Spawns at enemy death location, floats along nearest Ley Line to Gate, disappears on arrival - **Interaction**: Visual feedback of resource generation, player sees exact income sources ### Overload Field (AOE Effect) - **Sprite**: ProceduralSprite circle with expanding animation - **Appearance**: Expanding ring of electrical energy from the Storm Gate - **Behavior**: Damages all enemies in range, temporarily boosts Conduit damage - **Interaction**: Player-triggered ability via Gate click, visible area indicator shows coverage ## Core Loop ### Second-to-Second (ACTIVE GAMEPLAY) - Player watches enemies spawn and travel along Ley Lines toward the central Gate - Player identifies gaps in coverage and quickly places new Conduits at strategic junction points - Player clicks individual enemies to zap them with precision lightning strikes (skill shots) - Player drags between Conduits to create damage-dealing Links across enemy paths - Player monitors energy levels and decides when to activate Gate Overload for maximum effect ### Minute-to-Minute (STRATEGIC DECISIONS) - Between waves, player repositions Conduits to optimize coverage against new enemy types - Player upgrades Conduits to specialize them (range, damage, or special effects) - Player checks energy reserves and decides which element specialization to unlock next - Player views upcoming wave composition and adjusts Conduit element types for effectiveness ### Session-Level (META STRATEGY) - Player pursues a specific elemental build (air/fire/earth/void) that changes how Conduits function - Player decides between spreading Conduits wide for coverage vs. concentrating for power - The visual complexity increases as more Conduits, Links, and energy effects fill the screen - Player works toward accumulating enough energy to unlock the final Gate ability ## The 30-Second Gameplay Description A wave of dark Corruption Spawns slithers along the glowing blue Ley Line from the top-left corner of the screen. Your three Conduits pulse with electricity as they fire orange projectiles. You notice a gap in your coverage on the left branch - quickly click the empty junction point and place a new air Conduit that materializes with a crackle. A Storm Wraith teleports past your outer defenses, so you click it directly to unleash a precision lightning bolt that disintegrates it into sparkling particles. The particles flow like a stream along the Ley Line back to your central Gate, which pulses brighter as it absorbs the energy. You drag between two adjacent Conduits to create a glowing Link arc just as a Corruption Titan plods into view, and the combined fire tears chunks of its health away before it can reach your Gate. ## Currencies ### Energy (Primary Currency) - **Role**: Primary currency for building and upgrading - **Earned by**: Enemies drop visible Energy Orbs on death that flow along Ley Lines to the Gate; player sees every source of income visually - **Spent on**: Placing new Conduits, upgrading existing ones, repositioning Conduits - **Feel**: The immediate reward feedback loop - kills directly create visible energy flow ### Charge (Secondary Currency) - **Role**: Ability resource built through skillful play - **Earned by**: Creating Links between Conduits, killing enemies with precision lightning strikes, and timing Gate Overload to hit multiple enemies - **Spent on**: Activating Gate Overload AOE attack, unlocking elemental specializations - **Feel**: Rewards skilled play and active engagement over passive clicking ### Resonance (Prestige Currency) - **Role**: Long-term progression currency - **Earned by**: Completing waves without taking Gate damage (no enemies reach center) and surviving corruption overflow events - **Spent on**: Permanent elemental mastery bonuses that change Conduit behavior - **Feel**: The mastery currency that rewards truly skilled defense ### Corruption (Enemy Health/Threat Meter) - **Role**: Inverse currency representing enemy strength - **Grows by**: Enemy spawns, wave completion bonuses, enemies that reach the Gate - **Reduces by**: Using Energy to purify the Ley Lines (gradual reduction) - **Feel**: The pressure mechanic - higher corruption means stronger enemies spawn ### Currency Flow Energy builds Conduits and upgrades → Conduits kill enemies → Enemies drop Charge → Charge powers abilities → Abilities kill more enemies → More Energy. Resonance comes from skilled play (no gate damage) and unlocks permanent bonuses. Corruption is the threat that escalates if not managed through Energy expenditure. ## Progression Hooks ### Early Game (0-5 minutes) - The first "aha" moment is placing your first Conduit and watching it fire at an approaching enemy - the visual feedback is immediate and satisfying - Canvas interaction is immediately available: click junction points to place Conduits, click enemies to zap them - First unlock is the second element type, showing that Conduits can have different effects ### Mid Game (5-15 minutes) - Link mechanic unlocks: drag between Conduits to create damage arcs across enemy paths - New enemy types (Storm Wraiths with teleport, Titans with spawn ability) force strategic adaptation - Elemental specialization: choosing air (range), fire (damage), earth (slow), or void (corruption damage) ### Late Game (15-30 minutes) - Multiple Ley Lines active simultaneously with complex branching paths - Gate Overload ability unlocks powerful AOE attacks - Corruption overflow events: massive waves with special boss enemies - Visual complexity peaks with dozens of Conduits, Links, and particle effects filling the screen ### Key Milestones 1. Place first Conduit - see projectile fire and hit enemy 2. Kill first enemy - watch Energy Orbs flow back to Gate 3. Complete first wave without Gate damage - earn Resonance bonus 4. Unlock second element type - Conduits can now specialize 5. Create first Link between Conduits - enemies crossing take massive damage 6. Survive first Storm Wraith wave - adapt to teleporting enemies 7. Activate first Gate Overload - devastating AOE clears wave 8. Choose elemental specialization path - commitment to a playstyle 9. Face first Corruption Titan - boss enemy with spawn mechanics 10. Reach corruption threshold for overflow event - climactic final challenge ## Meaningful Choices - **Choice 1: Element Specialization** - **Options**: Air (extended range, lower damage), Fire (high damage, short range), Earth (slows enemies, moderate damage), Void (bonus damage vs. corruption, reduces enemy power) - **Tradeoff**: Each element creates a different playstyle visible on Canvas - air creates a perimeter of distant towers, fire concentrates damage, earth creates kill zones, void directly weakens enemies - **Visual Impact**: Different colored projectiles, different particle effects, different optimal placement patterns - **Choice 2: Spread vs. Concentrate Defense** - **Options**: Spread Conduits across all junction points for broad coverage vs. concentrate them in overlapping kill zones - **Tradeoff**: Spread covers all paths but has weak points; concentrate creates devastating kill zones but leaves some paths exposed - **Visual Impact**: Spread shows projectiles crisscrossing everywhere; concentrate shows intense localized battles - **Choice 3: Link Strategy** - **Options**: Create many short Links between adjacent Conduits vs. fewer long Links that require precise placement - **Tradeoff**: Short Links are easier to maintain but less damaging; long Links are devastating but break if one Conduit is damaged - **Visual Impact**: Short Links create a web of glowing arcs; long Links create dramatic electrical bridges across the battlefield ## Prestige Concept - **Trigger**: After surviving a Corruption Overflow event (massive boss wave at 25-30 minutes) or by voluntarily resetting after earning sufficient Resonance - **What resets**: All Conduits removed, Energy and Charge reset to zero, corruption level reset - **What persists**: Resonance currency, elemental mastery levels (permanent bonuses to chosen element), Ley Line layout upgrades (additional junction points become available) - **Prestige currency**: Resonance, earned through skilled play (no Gate damage) and overflow survival - **Acceleration**: Run 2 starts with one pre-placed legendary Conduit of your chosen element, 20% increased Energy gain, and immediately unlock Links. The Ley Lines have more junction points available from the start, allowing more complex placement strategies immediately. - **Visual transformation**: After prestige, the Storm Gate gains permanent elemental visual effects matching your mastery (lightning crackles for air, flames for fire, etc.). The background becomes more dramatic - more intense storms, more frequent lightning. Conduits of your mastered element have special visual flair and enhanced animations. ## Controls Display - **Left Click on Junction → Place Conduit** (costs Energy) - **Left Click on Enemy → Precision Lightning Strike** (costs Charge, has cooldown) - **Drag Between Conduits → Create Damage Link** (costs Charge) - **Click Storm Gate → Activate Overload** (costs Charge, AOE damage) - **Right Click Conduit → Reposition/Sell** (partial Energy refund) ## Getting Started Tutorial • Click on the glowing junction points along the Ley Lines to place Conduits • Corruption creatures are coming to infect your Storm Gate - stop them by destroying all enemies • Kill enemies to earn Energy, use it to build more Conduits and upgrade your defenses • Don't let any enemies reach the center Gate - perfect defense earns bonus Resonance for permanent upgrades ## Unique Selling Point The Ley Line placement system combined with the Link mechanic creates tower defense where positioning is everything - you're not just placing towers, you're creating an interconnected electrical network where the connections between towers matter as much as the towers themselves. Enemies aren't just blocked by damage - they're intercepted by the arcs you create between your defenses, making player-created pathways the central strategic element. ## Visual Direction Color palette: Dark blue and purple background (#1a1a2e, #16213e), bright blue glowing Ley Lines (#00d4ff), orange/yellow electrical effects (#ffd700, #ff6b35). The mood is stormy and dramatic with animated rain particles, periodic lightning flashes that illuminate the whole battlefield, and constant electrical crackling effects. Conduits pulse with their elemental colors when firing. Enemy deaths produce bright particle explosions that visibly travel along Ley Lines back to the center. The Gate is a constant visual anchor - the bright, glowing center that everything revolves around. ## Technical Scope Check - Canvas rendering with 5-6 sprite types using SpriteData and ProceduralSprite - ✓ feasible - Pathfinding along pre-defined Ley Line routes - ✓ simple, no complex algorithms needed - Projectile system with elemental variants - ✓ straightforward particle effects - Energy orb particle system flowing along paths - ✓ achievable with basic vector math - Wave spawning system with enemy types - ✓ standard tower defense pattern - Currency system with 4 interconnected currencies - ✓ standard incremental game systems - Prestige system with persistent bonuses - ✓ standard save/load functionality - Link mechanic between placed entities - ✓ requires distance checking and line drawing Complexity flag: The Link mechanic requires O(n²) distance checks between Conduits but with reasonable Conduit limits (20-30 max) this is negligible. The particle systems should be capped at 100-200 active particles to maintain performance.

# UI/UX Design - Storm Gate Defenders ## Overview Storm Gate Defenders presents a dramatic, stormy interface where the Canvas game world is the undisputed star. The visual identity draws from the theme of an ancient portal channeling elemental energy through a corrupted world. Deep blues and purples form the atmospheric background, while bright electrical blues (#00d4ff), gold (#ffd700), and orange (#ff6b35) create striking contrasts for game elements. The interface is designed around the central truth that this is an action-strategy game where players DIRECTLY interact with the Canvas. Every click matters - placing Conduits on junction points, zapping enemies with precision lightning strikes, dragging between towers to create electrical Links. The bottom panel supports this action but never replaces it. The HUD keeps essential information always visible without obscuring the dramatic lightning-filled battlefield. The mood is intense and electrical - constant motion, crackling energy, and the ever-present threat of corruption. The UI reflects this with glowing elements, smooth animations, and immediate visual feedback for every action. ## Color Palette | Role | Color (hex) | Usage | |------|-------------|-------| | Background (primary) | #1a1a2e | Main background behind Canvas | | Background (secondary) | #16213e | Panels, cards, bottom panel | | Background (tertiary) | #2a2a4e | Hover states, active elements | | Canvas background | #0f0f1a | The game world background (darkest) | | Text (primary) | #e0e0e0 | Main text, labels | | Text (secondary) | #a0a0a0 | Secondary labels, descriptions | | Text (muted) | #606060 | Disabled, locked items | | Accent 1 | #FFD700 | Energy currency, primary actions | | Accent 2 | #00D4FF | Charge currency, abilities, Ley Lines | | Accent 3 | #9B59B6 | Resonance currency, prestige UI | | Success | #4CAF50 | Affordable, completed, positive | | Warning | #FF9800 | Almost affordable, attention | | Danger | #F44336 | Cannot afford, Corruption, danger | | Prestige | #9B59B6 | Prestige currency, prestige UI elements | ## Typography - **Font family**: 'Orbitron', system-ui, -apple-system, sans-serif (Google Font: Orbitron for headers, system fonts for body) - **Headings**: Weight 600, size 16-22px (uppercase, letter-spacing 1px) - **Body text**: Weight 400, size 13px - **Numbers/currencies**: 'Orbitron', weight 600, monospace-aligned for tabular figures - **Buttons**: Weight 600, size 12px, uppercase ## Screen Layout ### Master Layout ``` +------------------------------------------------------------------------------+ | [HUD BAR - Always visible at top] | | ⚡ 50 | ⚡ 10/100 | ✨ 0 | ☠️ 0/100 | Wave 1 | ⚙️ | +------------------------------------------------------------------------------+ | | | | | | | | | | | [CANVAS - Main Game World] | | (~65% of screen height - 500-600px typical) | | | | - Storm Gate at center (glowing) | | - Ley Lines radiating outward | | - Enemies traveling along paths | | - Conduits firing projectiles | | - Energy Orbs flowing back to Gate | | - Links connecting Conduits | | | | | +------------------------------------------------------------------------------+ | [BOTTOM PANEL - Upgrade/Management] | | (~35% of screen height - 250-300px, collapsible) | | +------------------+ +------------------+ +------------------+ +--------+| | | CONDUITS | | UPGRADES | | ELEMENTS | | ⬆️ || | +------------------+ +------------------+ +------------------+ +--------+| | | [Conduit Cards] | | [Upgrade Cards] | | [Element Icons] | || | | | | | | | || | +------------------------------------------------------------------------------+ ``` ### HUD Bar (Always Visible, overlays top of Canvas) | Element | Position | Content | Behavior | |---------|----------|---------|----------| | Energy display | Left | ⚡ icon + amount + rate/sec | Count-up animation (300ms), gold glow on gameplay-earned | | Charge display | Left (next to Energy) | ⚡ icon + current/max (100) | Count-up animation, cyan glow on skill actions | | Resonance display | Center-left | ✨ icon + amount | Count-up animation, purple glow on perfect wave | | Corruption meter | Center-right | ☠️ icon + progress bar (0-100) | Fills red, bar changes color at thresholds | | Wave counter | Right-center | "Wave X" | Updates on wave start, 2s countdown before | | Settings button | Far right | ⚙️ icon | Opens settings modal | ### Game World Canvas - **Dimensions**: 900x500 (responsive, maintains aspect ratio) - **Background**: Solid color #0f0f1a with animated rain particles and periodic lightning flashes - **Layers** (drawn in order): 1.

Dark blob-like enemies slither along these paths toward the center. You click a glowing junction point and a turret materializes with an electrical crackle. It immediately begins firing orange projectiles at the approaching enemies. One enemy gets too close, so you click it directly and a lightning bolt zaps from the gate, vaporizing it. The particles from its death flow like a stream along the path back to your gate. You drag from one turret to another, creating a visible electrical arc between them. More enemies approach, crossing the arc and taking damage. The screen is alive with motion — projectiles flying, enemies dying, energy flowing, lightning crackling. - **Can you describe 30 seconds of gameplay without mentioning numbers, currencies, or upgrades?** YES - above description - **Does the player interact with the Canvas directly at least every 10 seconds?** YES - placing Conduits, Zapping enemies, creating Links - **If you removed all upgrade panels, is there still a recognizable game on the Canvas?** YES - tower defense gameplay exists entirely on Canvas - **Would a bystander understand what's happening?** YES - enemies attacking, towers defending, clear visual feedback ### Feedback Loop Completeness | Action | Canvas Feedback | UI Feedback | |--------|----------------|-------------| | Place Conduit | Electrical spawn animation, crackle effect | Energy counter animates down | | Enemy dies | Death particles, floating "+X ⚡" | Energy counter pulses up | | Buy upgrade | Conduit glows, projectiles visibly change | Card flashes green | | Wave complete | Screen flash, pause | Toast message, wave counter increments | | Zap enemy | Lightning bolt from Gate, hit flash | Charge counter animates down | All actions have BOTH Canvas and UI feedback. ### Reward Visibility Check At any moment player sees: - Next affordable Conduit/upgrade (cost visible in cards) - Next unlock threshold (progress bars on locked cards) - Current production rates (Energy/sec displayed) ### Variable Reward Check - Wave rewards vary (normal vs perfect wave bonus) - Different enemy types give different rewards - Milestones give diverse rewards (new abilities, visual changes) - Surprise elements: Wraith/Titan unlocks, Overflow events ## Quality Criteria Verification - [x] Canvas game world is PRIMARY (65% of screen height) - [x] Upgrade panels are SECONDARY (35% height bottom panel) - [x] Currency displays ALWAYS visible in HUD - [x] Every entity type has visual specs (state machines + CONFIG) - [x] Canvas layers specified (9 layers) - [x] Every UI element has specified states - [x] Feedback specified for BOTH Canvas AND UI effects - [x] Floating damage/reward numbers specified - [x] Color palette has sufficient contrast - [x] Tab unlock conditions match progression.md - [x] Number formatting rules cover full range - [x] Prestige UI shows visual transformation - [x] Accessibility basics covered - [x] Design works at 1280x720 minimum - [x] Canvas IS the game, not the UI - [x] Every entity has state machine diagram - [x] Entity interaction diagram shows relationships - [x] UI event flows cover all major interactions - [x] UI state machine shows game phases - [x] CONFIG.entities spec complete - [x] CONFIG.canvas spec complete - [x] CONFIG.ui spec complete - [x] CONFIG.effects spec complete - [x] CONFIG.colorPalette complete - [x] Permanent controls panel designed (5 actions) - [x] "How to Play" overlay designed (4 bullets) - [x] Controls panel ALWAYS visible - [x] Tutorial has dismiss button + localStorage
