First Person Tetris is a perception-bending rehash of the original Nintendo Entertainment System Tetris game where you assume the perspective of the blocks... while they turn. So, instead of the block turning, your perception of the playing field itself rotates, ramping up the difficulty of Tetris to new, vomit-inducing heights.
