in games folder? you mean in steam files or something?

Hello! i have just bought the steam version of the game, it says i can set keyboard keys to what ever i want, and when i do that and leave the game the customised keys are not saved. even when pressed on Apply. i really do want to speedrun this game but this issue keeps happening.

also, for steam version is there a way i can use a controller, my preferred method is to use a controller (x box 360 replica usb controller) how can i use a controller for this?
