This needs more ratings, what a gem! Great job on the game, it's fun to play. Only thing you could have a look at is making feedback for hitting and for dying clearer. I didn't realize the speed boss killed me since I still had a bit of life left and it felt I passed the stage and got to the next when in reality I had died and the game immediately restarted. Also the hit is not clear, as the sound plays for every press of the spacebar but the animation takes much longer and it felt to me that I could actually hit faster than the animation would suggest. :)
