Yeah really not sure why we had such a hard time getting controllers to work universally, many 3rd party controllers just don't work without steam overlay but some only work with it disabled? Definitely some weirdness going on there. You can in fact okay with keyboard, W/S and Up/Down arrow keys + both CTRL keys brake. It doesnt feel quite as good imo but it works. Thanks a ton for giving our game a shot and leaving feedback!
