Open-source platform webgame Author Danny Hendrix This game gives an example of a setup for a HTML5 game. The game is written in Dart (http://www.dartlang.org/). Demo is available on http://www.dannyhendrix.com/dart/platformgame . To improve performance, the level is buildup from tiles. Objects move from tile to tile, only the tiles that have changed are repainted each frame. Objects are pre-rendered on separate canvases. More information on performance improvements used in this game: http://www.html5rocks.com/en/tutorials/canvas/performance/ Feedback is always welcome :).
