An interesting
Warp Zone note:
In
Super Mario Brothers 2, the
Japanese version (ie: not the version based on
Doki Doki Panic), there are
warp zones that take you not ahead, but
backwards. At the end of several of the
underground stages, you cleverly jump the
bricks surrounding the
pipe, where you find
yourself with the only options being to either let time run out so that you
perish, or go back to
world 1. Either way, you feel like a
complete moron, and some Japanese
programmer has had yet another
chuckle, at your
expense.
