Alright now that the game's actualy playable, here's some bugs that didn't kill it completely:
-The game soft-locked while Chuck's dialogue about betraying him started when I was off screen
-I killed the boss and died in what I think was the same frame, so the regular level music and the game over theme played over each other
-the grim reaper guys knocked me into a wall I had to wiggle to get out of
-In the room after the boss the game started running at halfish speed and the background started to wig out
-At some point leaving it idle while typing the above out it started to worsen
-eventually it crashed and it now exists only as an icon in volume manager
-the candle dudes' fire seems to not do damage to anything
