Loop Hero seems to think I have a gamepad connected. I can see controller button overlays, and the mouse does not function properly. If I launch the game from a terminal, I see many status messages referring to gamepad detection. There are many lines reading, "Hmmmm we don't think this is a joystick!!!!!".

This is preventing me from playing the game. Does anybody have a suggestion for me?

Update: I was able to operate the mouse by pressing F8 .

Thanks ! I was having the same problem. Weird fix, but glad it works !
