Cascade Countdown

Cascade Countdown is a hand-tracked physics arcade game built for Apple Vision Pro. Glowing 8-colour plasma cubes — randomised sizes, real physics — cascade down through spinning bumpers and a prism splitter onto tilted catch plates in your room. Reach into the cascade, pinch any cube mid-flight, and throw it into the floating goal ring. Every collision synthesises a chime pitch-snapped to the key, so the chaos harmonises into a tune that rises with the action. Poke START and you've got 30 seconds. Keep cubes alive. Score every goal. Post your three letters to the global top-20 leaderboard. —— GAMEPLAY —— • Pinch-to-grab and throw any cube with either hand — anchored to your thumb tip, follows your throw velocity • Two-hand pinch to scale and rotate the whole world via the floating chrome handle • 30-second time-attack mode with a global top-20 leaderboard • Set your own three-letter player tag on the in-world YOUR TAG panel — your scores post under your name • Grabbable HANDS / START / MUTE / GESTURES / SKY / RESET control panel — move it anywhere in your space • Real-time procedural soundtrack — every cube collision is a synthesised chime, pitch-snapped so the music never breaks —— TECHNICAL —— • 90 FPS locked — zero variance across a 95-second sample • Mixed-immersion passthrough — cubes composite into your real room, not a virtual one • ~475 physics collisions per round, simulated on-device • System wrist menu suppressed during play for uninterrupted immersion • No ads, no tracking, no account required —— BUILT WITH —— Cascade Countdown is built on the open-source Godot game engine using Apple's official visionOS contribution (Godot PR #109975, Ricardo Sanchez-Saez / Apple visionOS team) — the first publicly-documented Godot RigidBody3D physics scene rendering in immersive mode on real AVP at locked 90 FPS with working hand-tracking pickup. Hand tracking runs entirely on-device through Apple's hand-tracking system. No camera data ever leaves your headset. —— PRIVACY —— Cascade Countdown collects no personal information. The leaderboard transmits only your chosen three-letter tag and your round score. There are no ads, no analytics, no tracking, no third-party SDKs. Made independently by Alex Coulombe.
