A patch already?! I was a little shortsighted in how I set up the controller systems in the initial release, and as there are no Keyboard/Mouse controls in the game I did a complete overhaul to support a much larger number of assorted gamepads (see full list below) . Unfortunately if your controller is not listed, it is unlikely that it will be supported in the future. They have each (obviously) not been individually tested, so let me know if you have any issues and I can look into it. 

If you did give it a go, I appreciate the time you spent trying this little experimental game. Please consider rating/reviewing and if you're feeling super generous, donating.
