This may be a one year old thread that has long since died, but if this game ever gets updated again there should be control configuration, as its kind of hard to hop to this game from a game that uses traditional controls (WASD, space, and even the mouse button)
or maybe I'm just autistic and have bad motor functions when something changes too suddenly
But the game is good, and I would love to play it even more if it weren't for the controls
