Super Meat Boy is the poster child for tough-as-nails precision platforming. The 2010 2D platformer starring a slab of meat was a viral hit in part because the game knew how difficult it was, and emphasized your repeated deaths by showing you each of them simultaneously once you finally completed a level. I've been curious to see how that 2D precision would translate into the realm of a 3D platformer. Unfortunately, based on a brief gameplay demo, the answer is: not very well.
