I know this is gonna sound REALLY stupid, but is there controller support? I wanna try the game out, but I've played console for so long that I play like a 6-year-old on K&M.
The early access version on Steam has partial controller support. This means it's playable with a controller, but the menus dont work yet and you can't rebind any buttons for it yet. Those are coming later, but are not a priority.
