I really enjoyed the music and some levels! I would appreciate having some feedback on how much force I'm using when throwing magnets. One possibility would be to show the trajectory, but that would probably just mess the difficulty. But if you would draw an arrow and number of newtons or something, that would be really cool. Game esthetics reminds me of school physics problems anyway. But the overall nice game I must say. Unfortunately, I encountered a bug when the next level doesn't load two times (web version - chrome).
