Personally I loved how schizophrenic the game's aesthetics were. Made it feel unpredictable and dangerous! Never knew what form the next chapter would be taking.
See, I'd be OK with the the "schizophrenic" approach if the majority of the game was good. Unfortunately, I felt only a handful of the ideas thrown at the wall worked.
Mind you, as critical as I am of the first game, I would love to see the concept done well. I think it could make a great game.
