Hauberk
A web-based roguelike written in Dart
...The game runs directly in a web browser after its Dart source is compiled to JavaScript. A local development command starts a server that recompiles source changes automatically during development. Its codebase has also served as the origin of reusable Dart libraries for terminal rendering and 2D game utilities. The permissive MIT license allows developers to study, modify, or use the project as a foundation for their own games.
