I'm on the fence about this game. On the one hand it's a fantastic platformer that has a great vibe and lovely graphics. On the other hand the collectibles and missable nature of a lot of them is driving me CRAZY, to the point of wanting to throw my Pro controller at the television. I get they're there for increased challenge but having to collect four different things on every level is just maddening. I think I might just stick to the wonder wool, for my sanity.
PS: Pyramid level in World 2 was great fun, except for the upwards escalator which made me feel like yelling very very loudly.
