Must..not..rage-quit >.<
Good game, just reeeeeally annooying (and frustrating) in some levels; but that was to be expected uh?
It isn't 5 stars only beacuse you could have added some sort of...funny story, lame jokes and so on.
I KNOW it isn't simple and it isn't anything new, but for this kind of game you could have added something (ever played "Portal" ?).
Also some effects, not only the "biiiiiiiiiiiiiiiiiii" sound when you touch a skull-block.
