Hi all! I recently tackled a bounty in porting Open Tyrian to the OUYA, but there seems to be some bugs. I never played the original version, so I overlooked some things (such as rear shooting) that should be tied to buttons. Nonetheless, the version that you might find on the current OUYA Discover store has the code available here: https://github.com/HeinousGames/commandergenius. If you’d like to help in updating it, please feel free to open a pull request!
It’s available on the server: http://ouya.cweiske.de/game/com.googlecode.opentyrian.htm
