I messed a lot with the physics to give the player more control with how the marbles move, so yes, it can be a bit weird at the start, haha. Mmm, the camera controls were tough to figure out, there's a lot of verticality in some of the levels. When I did have W/S take you forward/backward, it was really annoying to go up/down so it was kind of a lose/lose situation. XD
