My game wasn't working as intended and after a while I realised pressing Shift = Pressing button O on the Ouya controller. The strange thing is this even works without the Ouya object.
The arrow keys also move the dpad or left analog stick.
I'm not totally sure how many of the Ouya buttons are mapped to the keyboard, maybe someone from Clickteam can help me here?
The best part is the game didn't crash when i held down a button whilst changing frames, so maybe that can help people getting their games rejected?
