I'm not sure if this has happened to anyone but me, but I use a black Xbox 360 controller to play this game. I connect it using a Microsoft Xbox 360 Wireless Receiver for Windows. When I play Super Meat Boy, the A button seems to not work well. In a game where jumping is necessary, this causes issues for me. The A button works well in other games (e.g. Rogue Legacy, Offspring Fling, Portal 2, etc.) but not this one. Does anyone have any helpful tips/advice on how to fix this?
