Review on JGame by Michael Skerving

The simplicity of creating your own unique game using very basic coding skills (or even no coding at all). You can use any programming language you like to write code for it. It's cross platform so works in virtually every browser out there without modification. There are some bugs but they aren't really big ones - most people seem happy enough just playing around with what it has already got. I'm developing my first mobile app/game hybrid here. Its not as polished or easy to work within as Unity or Cocos2d etc., its less expensive too which is key for me. It gives me total control over how everything looks and functions.
