A cool concept and very impressive for a weeks work. Not sure if it was intentional but I found I could get through everything other than the hammer levels easier if I mostly ignored the cubes and just pushed the ball around.
Yeah it is intentional as there's supposed to be consequences for it. Although from the feedback so far I think it's not "punishing" enough, especially as you can cheat it (people already found it almost immediately after I uploaded the game ;-;). Also, thank you !
