I’ll be in London from Thursday to Monday presenting on HTML 5 game development at the Mozilla Festival.
I’ve been working on an HTML 5 side-scroller, as yet unnamed. The plan is to have the game skeleton pretty solid before my session, and then have participants in the session hack on it, add features to it, and flesh it out. That way the participants can get to work on the fun parts of game development, like creating monsters and power-ups, instead of spending the whole session setting up boilerplate code and debugging their event handlers.
The code for the game is on GitHub and there is a playable version hosted on my site. It uses BrowserID for the login. You can give it a try right now — log in and try making a level with the level editor, or play one of the existing levels and try to beat the best time! If you find bugs, please report them in GitHub. Thanks!
