Really awesome game and definitely one of the most innovative ! I had quite some trouble getting through the tutorial at the beginning, but after getting through it things started to make sense and the fun begins. I would suggest lowering the tutorial's difficulty a bit though ^-^". At level 2 i also found myself hitting the spikes although i was not touching them visually. I think the spike hitbox there should be smaller. Other than those, I don't have anything else to complain. Once again, really awesome game !
