The rotation mechanic is interesting, mightve felt smoother if you could rotate clockwise or counterclockwise (with different keys) instead of just in one direction tho. I agree with Palmasop, the door in level 1 was pretty confusing, had to retry the level a bunch to figure that out. Small side note, in level 1, for the button that shoots a square at you, the square stays in the same position on the screen through rotations, not sure if that was intentional or not....
Overall fun game!
