wow :O
that was one of the most entertaining madness animations ever ;) no jokes.
there was one bit i spotted which was at the end in the room before the 'power 10% room', when he picks up the shotgun it stops glowing green. Thats no big deal though in comparison the the amazing amount of effort you must've put in to this, I will give this a 10/10 because you clearly didn't rush any parts and you put alot of time into it, it payed of well :) nice on :D I'm looking forward to any more of your animations.
p.s. nice choice of music :P
