This little Platventure is wonderful; you explore a small dungeon, using glitch powers to solve traversal puzzles and find hidden items.  Boss fights are occasionally frustrating (just one in particular, in my case), but you can always come back with more life by beating others.  What really makes this shine especially brightly is how it beautifully captures the weirdness you'd find in the darkest depths of an old NES title.  The music doesn't sound like the NES, but that doesn't matter because it's spectacular.
