There's some evil stuff in here. I realize the real super mario bros 2 (the lost levels) has the poison mushroom immediately upon starting it so that's the real origin point of evil mario levels, but there's some wild level design in here! It also feels a bit like Doom (ironic because this game was part of the inspiration for doom) in the way that there are hundreds of tossed off ideas in here that could be whole games, and eventually someone else WOULD pick them up and make them into their own games. Cool ass object, still fun to play, hard as hell.
