KAIRO

KAIRO

One button. One line. One perfect moment.

You drift right by default. Hold to go left. That's the entire control scheme.

Slip through each gate to survive — anyone can do that. But hit the exact center and your multiplier climbs, the music gains a layer, and everything speeds up. Miss the center and it all resets.

Every gate is the same question: play safe, or chase the perfect line.

Two modes Daily — 100 gates, one life, the same course for every player in the world. Resets at midnight UTC. Endless — random seed, unlimited runs, no finish line.

Built with No engine, no framework, no external assets. Vanilla JavaScript and Canvas 2D. Every visual is drawn procedurally and the entire soundtrack is synthesized live with the Web Audio API — the music is generated by how well you play, not streamed from a file.

Total build size: 100 KB.

Feedback welcome — especially on difficulty and whether the multiplier system reads clearly.
