v1.4.2 — Latest Release October 2026

Multi-Device Touch & High-DPI Canvas Polish

Version 1.4.2 focuses heavily on touch input latency optimizations on modern mobile OLED displays and fixing slight sub-pixel anti-aliasing blur on Apple Retina displays.

Touch & Control Enhancements

  • Reduced Touch Input Latency: Implemented passive event listeners for pointer and touch interactions with touch-action: none, eliminating the 150ms 300ms double-tap delay on WebKit mobile browsers.
  • Added French AZERTY Keyboard Support: In addition to Left/Right arrows and standard A/D, players using European AZERTY keyboard layouts can now utilize Q/D naturally.
  • Visual Touch Indicators: Improved tactile visibility of left and right touch zones for handheld mobile and tablet gameplay.

Visual & Rendering Polish

  • Retina & 4K Sub-Pixel Scaling: Synchronized canvas device pixel ratio calculation with Math.min(window.devicePixelRatio, 2) to prevent excessive GPU strain while ensuring razor-sharp edges on high-density displays.
  • Audio Node Garbage Collection: Fixed minor memory accumulation in procedural oscillator nodes during extended play sessions.
v1.4.0 September 2026

Endless Survival Mode & Celestial Flow State

This major update introduced the high-stakes Endless Survival mode alongside the Flow State bonus coin multiplier for sustained precision balancing.

New Game Mechanics

  • Endless Mode: Added an un-capped survival mode that progressively scales wind speed, random gusts, and directional cross-shears every 10 seconds of survival.
  • Flow State Mechanic: Maintaining balance within ±4 degrees of vertical for more than 2 consecutive seconds activates the celestial Flow State, providing a gentle synthesized chime and awarding continuous bonus coins.
  • Local Best Tracking: High scores for Endless runs are now preserved in browser LocalStorage with 0.1-second decimal precision.
v1.3.0 August 2026

The 4 Worlds Expansion & 30 Levels

Expanded the initial prototype from a single looping stage into a full 30-level progression spanning four distinct atmospheric biomes.

World & Level Additions

  • World 1: Dusk Peaks (Levels 1–8): Introductory mountain sunset atmosphere with gentle wind tutorials.
  • World 2: Midnight Sky (Levels 9–16): Introduced wandering sky birds that collide with the balance pillar.
  • World 3: Neon Storm (Levels 17–24): Introduced lightning flash warnings and sudden gust reversals.
  • World 4: Solar Zenith (Levels 25–30): Extreme thermal updrafts with tightening fall thresholds (down to 38 degrees).
  • 3-Star Evaluation Formula: Implemented a tiered scoring metric requiring both stage survival and 100% orb collection for master rank.
v1.2.0 July 2026

Procedural Web Audio Engine

Replaced external MP3 sound files with an entirely self-contained procedural Web Audio API synthesizer.

Audio Architecture

  • Zero Audio Network Requests: Eliminated all external audio file downloads. Every chime, gust, and fall sound is synthesized in real time via native Web Audio API oscillators and gain envelopes.
  • Dynamic Harmony Synthesis: Star clear fanfares now dynamically calculate pentatonic frequencies on the fly.
  • Browser Mute Compliance: Added immediate audio context suspension whenever the user leaves the tab or clicks the in-game mute toggle.
v1.0.0 — Initial Release May 2026

Initial Engine Launch

The birth of Wobbly Spirit on bodybalance.tech.

  • Core inverted pendulum physics simulation running at fixed 60Hz.
  • Initial cosmetic skins: Lumina, Ember, and Zephyr.
  • Zero-download browser execution with native canvas rendering.
