Well that was interesting. The levels were pretty easy for me. The only part were I struggled was on the level before the boss fight towards the end. Seems theres no way past without taking some damage?
Epic boss fight though. Really neat concept actually. Not something I would have ever thought of. +1 for tetris too :D
EDIT: Forgot to add that the music was really hard to stomach. Really wish there was a way to turn off the lag there.
