From the README

A block puzzle built from real polycyclic aromatic hydrocarbons. Benzene to coronene, on a hex grid, drawn as proper Kekulé structures.

▶ Play in your browser · Also on itch.io · 日本語 README

No install, no build step, no account, no tracking. It is a handful of static files served straight from GitHub Pages.

Falling — molecules drop like Tetris. Steer, rotate and clear full rows before they stack past the red line. Speed climbs with the level, which rises from both lines cleared and time played, so a round that never completes a line still ramps up.

Placing — no clock.
