This game is self aware about what it means to be a platformer. It brings with it a dialogue about its own existence within a rich history of games like it. You speak back to it by playing it. Its smart witty and fun. Unless youre a complete tool like some of the reviewers here you should definitely get that giddy wow factor.
Spoiler alert.
Beyond its self aware narrative it also takes a braid-esque like approach to game mechanics (use an element always present and usually taken for granted and make it the core theme of the game), allowing you to change the flow of the game as you play by incorporating yourself (your characters corpses) into the level design. In that regard it reminded me a bit of Autocannibalism, but much more meta.
