So it happened three times that chocolate was taken literally?
At least this "chocolate" entry has more meaning and direction, even if I don't understand the point of the mask shop.
ZMann's entry (not made of chocolate) stayed very similar to the original game, except for speeding up a few things (enemies and conveyor belts), and putting in one of the few custom bosses that's easily available. Word has it that custom bosses programmed for special occasions (such as SMWCP) aren't publicly shared due to their rarity and difficulty to code.
