Update:
Due to an unfixable bug in the Mac version, we don't support 360 controllers on Mac. I do apologize for this. The bug is unfixable because I can't again risk killing everyones game with another update. The game incorrectly assumes that no more than 12 buttons will ever be on a controller. This is mainly true, however Mac controller drivers map the JoyHAT as 4 different buttons it seems, which makes it so you can't map B X and Y properly. This also messes up the start and select buttons. It was a mistake on my part. The bug could be fixed, however there is a significant risk that fixing it will break other things to the point where its unplayable with the keyboard which we would then have to go in and fix and start a whole new cycle of updating the game / breaking something in an update, rinse, repeat. I am sorry about this, do know that it is fixed in our new engine for game 2. Also, non Xbox 360 controllers appear to work fine. Joy2Key esque programs may remedy this issue, but it has not been tested by me. Again, we are sorry about this.
