I was replaying your game (again) and I found some bugs:
-in level 4, you can't see the first platform because of the jump button
-I am still bad at level 5
-when you pass level 6, you go to a place saying "to be continued", I didn't knew that there was a level 7! is confusing
-In level 7, when you enter it there is a fireball that moves with aaron
-I shoot like 10 fireballs and my game just froze
