I enjoyed the game, but I think maybe it could have benefited from more sounds or music. My only real complaint was when a mini-boss appeared the green background changed to a brownish color and that made is very difficult to see the bats for me. I think it was a harsh contrast and made the game artificially more difficult. A common problem with these games is that after several levels the game starts to lag like crazy. I think I had all of my abilities at level 8-9 except health.
