using a ps3 controller, at first it was recognized and I could play it normally but suddenly it stopped working and I can' t get it back to a functioning state. tryed reinstalling, changing controller mapping, changing to a different ps3 controller and using the cable without bluetooth but nothing so far seems to have worked. I accidentaly found out that if I hold the playstation button and move the joystick it counts as moving the mouse and I can also take screenshots and some other random sutff, not sure if this is a clue or a feature that I was unnaware of.

Trying to close the game normally, i.e. by selecting exit, does not really close the game. The screen goes black, silent and unresponsive, to go back to the desktop and tell steam to close the game I usually just use the command key.
