Prelude of the Chambered in Dart
Play it here.
Based on this java code by Notch: https://github.com/skeeto/Prelude-of-the-Chambered
This code is really ugly right now, but it matches the feature set of the original game. I'm going to be refactoring it whenever I have the time to be more organized. A lot of the game logic was copied straight from the source of the original Prelude of the Chambered by Notch, but the rendering code had to be rewritten for the most part to work with webgl.
This code uses DTMark extensively for texture loading, audio, and sprite batching. https://github.com/unknownloner/DTMark.
