I tried this earlier and this is a fun idea, especially if
M/J played it against each other. The only sad thing is
I had to play it alone lol XD. Maybe if you toy with AI
it would make for a good challenge.
Only tidbits I've got is I wish blake and whitley landed
on the platforms on their exact edges instead of kinda-in the middle as
it was hard to gauge when it's safe to jump.
