I built a small game in just 24 hours for a 64x64 pixel art lowrez game jam. The result is soko64, a tiny Sokoban game written in Dart.
This project was primarily a first test for a new web game library I've been developing for Dart (Bullseye2D). I wanted to see how quickly I could build a complete, playable game with it.
You can play soko64 directly in your browser: https://joemanaco.itch.io/soko64

Happy to answer any questions! :)
