Why Strata
- Four-lane 3D highway — gems fly toward you through a stratified neon canyon; hit them exactly where the light crosses the road.
- Beat-built levels — every track is generated from a seed, so the same seed gives the same song and the same chart, every time.
- Perfect · Great · OK — tighter timing scores more and feeds your combo; sloppy runs drain your life bar.
- Live synthesized sound — kick, hats and lane tones are generated in code by WebAudio. No audio files, pure browser signal.
- Keyboard & touch — D F J K on desktop, four tap pads on phones. Runs anywhere WebGL runs.
How to play
Goal: survive a 75-second seeded track with life left. Missed gems drain LIFE; your score grows with combo, so aim for PERFECT hits.
| D F J K | strike lanes 1–4 |
| ← ↓ ↑ → | same four lanes |
| Tap pads | the four bottom buttons, on touch screens |
| Space | start a run · restart after win or loss |
Life hits zero → SIGNAL LOST. Finish the track → TRACK CLEARED.
