Howdy, the only controller I have is a gamecube controller. I have the xbox 360 controller emulator x360ce and it seems to be working within the emulator, but it's very buggy in Steam big picture and Celeste doesn't even recognize it. In steam big picture, only the "B"  and left analog stick inputs are picked up, and the left analog inputs are extremely laggy (I can only navigate 3 menu items at a time). I know this may not be possible, but any advice or things I could try would be helpful. Thanks!
