Mod Edit: Split from "What Are You Playing Now", because it seems to deserve its own thread 
I've been playing the shit out of Super Meat Boy again. I realized that the Warp Zone Bandage Glitch erased some of my level completions, and of course it was on some of the most brutal levels in the game. But I only have four of them left now, as opposed to the approximately twenty five that I initially had to redo.
