This game is far too hard and the boss fight is crap. I have tried 274 times (tallied on paper) to pass the first and second part combined and I keep dying on the boss fight aka Just Impossible. Yes, the boss fight is impossible with all the boosts. The entire game is far too difficult for anybody to play. However, I will give a compliment to soften my criticism: The concept is good and so is the game when you don't keep dying.
Edit: Sorry, the boss fight is actually goddamn unplayable.
