What this is
A community port built on the original game, with room for new experiences.
Made for the browser
SpiderMonkey 128 runs the game scripts inside WebAssembly; the AI runs on its own thread.
WebGL 2 rendering, with frames capped at 30 FPS.
Load once. Play again.
Game archives are streamed in blocks and kept in IndexedDB, so a second visit starts quickly.
One engine. New ways to play.
