Show HN: Balancing game for the mobile browser with increasing difficulty

Original Article ↗ Hacker News Discussion ↗

A browser-based 3D balancing game that uses phone tilt and keyboard controls is drawing praise for its smooth physics, nostalgic Marble Madness/Monkey Ball feel, and clean Three.js implementation. Players highlight issues with device orientation, limited lives, and mobile/Firefox compatibility, suggesting features like configurable neutral tilt, checkpoints or “casual” modes, leaderboards, and better visual cues. Some also experiment with unintended strategies such as flipping the phone to “fly” through levels, pointing to both fun exploits and physics edge cases.

Overall Reception

  • Many find the game “very cool,” polished, and responsive, especially for a browser title.
  • Several players completed all levels, sometimes on the first run; others quit due to frustration with the punishment system.
  • Nostalgic comparisons to classic ball-rolling and platform games are frequent.

Controls & UX (Mobile vs Desktop)

  • Core mechanic uses the phone’s accelerometer; arrow keys / WASD also work on desktop and are widely praised as intuitive and precise.
  • Major pain point: neutral orientation is fixed to a flat, horizontal phone, forcing uncomfortable posture (e.g., lying in bed).
  • Suggestions:
    • Calibrate zero at start and via a “reset orientation” button.
    • Add a bubble-level or other visual orientation indicator.
    • Match camera to a top‑down view if “flat” must be neutral.
  • Some users initially didn’t realize tilting was needed; clearer instructions and visible start button in landscape are requested.

Difficulty & Lives System

  • Global 3‑life limit across all 10 levels is highly controversial.
  • Critics call it tedious and “artificial difficulty,” causing rage‑quits and preventing later-level exploration.
  • Supporters argue it adds suspense, preserves challenge, and prevents trivial completion.
  • Proposed alternatives: per‑level lives, checkpoints, infinite retries with a death counter, optional “zen/story” mode, or a separate hard mode.

Bugs, Exploits & Edge Cases

  • Known issues:
    • Ball can fall forever off some edges without triggering a new life.
    • Finishing from underneath the goal tile sometimes counts as a win.
    • Starting while not flat can cause instant fall with no reset.
  • Exploit: flipping the phone upside down lets the ball “fly,” enabling extremely fast clears.

Compatibility & Performance

  • Mixed reports on Android (Chrome, Brave, Firefox) and iOS/iPad; sometimes no motion detected or no permission prompt.
  • Some note Three.js generally runs smoothly on old phones, but React-based games can be slower.

Requested Features & Enhancements

  • Leaderboards (especially for speedruns), performance stats per level, daily/Wordle-style mode, PWA support, camera angle shifts with tilt, improved lighting/shading, level editor, and cosmetic additions (e.g., a character inside the ball).
