From the README

A modern, web-first reimagining of Crimsonland: a top-down twin-stick alien-hive survival shooter. One TypeScript codebase ships to **Web (primary, incl. mobile browsers)** and, via Capacitor, iPhone and Android.

v2. A run is a 12-minute arc with a win: swarm events at 2:30, 5:30 and 8:45, a midboss at 4:00 and 7:30, and a PRIME boss at 10:30. Kill the PRIME to clear the world, then EXTRACT or push into OVERTIME.
