This room used to have a coin cloud game, but it was removed due to its unfairness (sometimes, it's impossible to collect a coin)

Underwater shelljump?!? (Note that you can't jump in this room, so you can't swim up)

Can't Mario got up the pipe on time?
Also, I'm going to release a 2-levels demo (or 3 if I finish the third stage on time) in this C3. I'll have a lot of thing to do with this hack.
