I beat Atomic Robo-Kid Special today after working on it for a couple days, and I also noticed that Act 21 seemed to change up between playthroughs. Since one or two of the earlier Acts have multiple exits, I'm guessing it may have something to do with that.
BTW I also like this game a lot, though the final boss is aggravating and a couple stage enemies are too.
