Fantastic.
Wonderful game, clever story and enjoyable antagonist. First play through probably took me 40 so minutes. Even after I beat it I kept coming back to get the rest of the Medals. with a total of 343 I've finally gotten them all.
Beating it without dying is a pain, mostly because of the very beginning of level 9. Oh and one time I beat the speed run at EXACTLY 3:00 and it didn't give me the Medal...it does say "under".
Anyway, fantastic game. The level editor is great too, I played other peoples levels some were challenging most were just plain broken. Those complaining about the difficulty, thank you, you make completing the game that much enjoyable for the rest of us.
