Don't think it's a particularly "killer" art style... at all.. and the trailer isn't showing anything crazy in terms of puzzles...
Though anything with the promise of intricate and clever puzzle is a nice plus for platformers - just need to actually see if that's true, and being off on the artstyle isn't boding well :P
