you know how good the design is, so let me tell you about other stuff, first, the steam version is kinda buggy. It has vsync issues and stutters ever so often, usually in later levels, which can be very frustrating as it can also effect meat boy's physics. The game isn't unplayable on steam, but you will die more because of it. Inputs can and will be eaten every once in a while so that's fun. Also the characters and cutscenes haven't aged the best with newgrounds humor baked in but this doesn't impact the levels. Otherwise it was extremely doing both light and dark worlds.
