A couple of years ago I started working on a casual game in AS2 called Five Phases. The concept was based around the five phases of Chinese mythology and their associated elements and attributes. Essentially you combine five colored stones to release their energy.
Recently I started converting / refactoring Five into a Flex AS3 project. The resulting alpha release is below. I haven't bundled any instructions in yet, so I'm posting a brief rundown below the game.
