- EffectsManager handles all powerup visual feedback in one place
- Replace circle trail with proper effects per type:
* Rocket: yellow->red flame particles from feet + occasional bright spark
* Propeller: white/blue wind streaks around player
* Spring: gold/green spark trail while ascending fast
- Boost start burst: two expanding rings + radial sparks + camera shake
(orange/gold for rocket, cyan for propeller, green/gold for spring)
- Boost end puff: gray smoke cloud spreading from player
- Screen edge speed lines during boost (alternate left/right edges)
- Player no longer tilts with horizontal input during boost; rocket
stays rigid upright with tiny lean, propeller has gentle sinusoidal wobble
- Extract createButton/pixelText helpers to src/utils/ui.js with
sensible defaults and per-call option overrides
- MenuScene now shows BADGES button opening the achievement panel
(10 entries, count of unlocked, star icons for completed)
- GameOverScene buttons migrated to shared utility, removing duplicate
hover/click handlers
- Smaller LEADERBOARD button to make room for BADGES alongside
- AchievementsManager with 10 unlockables and toast popups
(Genesis Block, Chain Reaction x3, Bug Hunter, First Flight,
Liftoff, Power Trip, Survivor 500, Skyscraper 1000,
Speedrun 100/60s, Gas Baron 50k)
- Score popups: +N text floats above player on every landing
(gold and larger for genesis platforms)
- Powerup duration bar in HUD bottom, color-coded per power-up,
uses scaleX for smooth depletion animation
- New enemy: Failed Tx, falls from above with sine drift, unlocks
at difficulty > 800, can be stomped, tinted red
- Dynamic background: dark cosmic overlay alpha scales with height
(max 0.5 at very high altitudes)
- Achievement hooks integrated into ScoreManager, GameScene
- Combo no longer resets if combo was already 0 (was triggering log spam)
- SoundManager via Web Audio API (no asset files needed) with procedural
SFX for jump, spring, powerup, stomp, break, death, milestone, new-best
- Sound persists mute state in localStorage; mute button on Menu and Game
- Pause system: ESC key or onscreen pause button, modal overlay with
Resume and Main Menu options, physics correctly paused/resumed
- First-run tutorial overlay explaining controls and platform types,
dismissed and remembered via localStorage flag
- Touch indicator hints fade after 3.5s on touch devices only
- Menu start triggers AudioContext initialization (browser autoplay rules)
- GameOverScene supports ENTER/SPACE shortcut for retry, NEW BEST text
now pulses, sounds fire on each transition
- Fix Rocket/PropellerHat hitboxes (relative to sprite size, not magic offsets)
- Spring now destroys itself on use with squash animation instead of staying invisible
- Guard all powerups against double-trigger via consumed flag
- Save genesis glow tween reference for clean destroy
- Player.die() disables collisions (no more post-death platform bounces)
- Replace hardcoded enemy spawn cap 0.5 with DIFFICULTY.maxEnemyRate
- Enemy spawn position now anchored to platform X (-60/+60), not random
- Powerup spawn clamped to screen bounds
- Skip powerup spawn on breaking platforms (was unfair)
- ScoreManager.addPoints() public method; remove direct score mutation
- HUD elements use setScrollFactor(0) instead of per-frame repositioning
- All magic numbers extracted to SCORE / PHYSICS / POWERUP_DURATION config
- Remove dead code: showDeathVignette, drawDebug, createParticles, deathOverlay
- Remove dead constants: PLATFORM_WIDTH/HEIGHT, PLAYER_MAX_SPEED, tileBias
- Remove SUBMIT TO CHAIN fake button, replace with Coming Soon text
- Safer cleanup loop: collect-then-destroy instead of mutating during iterate
- gwei particles now have setScrollFactor(0.3) for parallax depth
