Jeff Weber's Mix 10k challenge entry didn't win any prizes, but it still stays a cool Silverlight game!
In his latest blog post Jeff guides you to the implementation of We Are Bugs and two of the patterns he used - Model-View-Controller and State pattern. Complete source code is available for free in a new CodePlex project. As Jeff says:
Feel free to do pretty much whatever you want with the source. Learn from it, extend the game, make derivative games, etc… I don’t require anything specific, but a shout-out to Farseer Games is always nice. :-)
