About this game
Match the roughly 80-second odd-meter song “Seven Claws,” synthesized on the fly with the Web Audio API, and hit notes on four lanes with the D, F, J, and K keys (or arrow keys, or taps). There are three difficulty levels—EASY / NORMAL / HARD—and four judgment types—PERFECT / GREAT / GOOD / MISS—with a maximum score of 1,000,000, ranks from S to D, and your best score saved in the browser. Beside a highway drawn with Three.js, a fan-made character based on Anthropic’s Claude Code mascot “Clawd” dances to the beat. It’s a single-file index.html setup requiring no build, and it also supports audio latency correction and pausing.
