Well, if the only pro is patterns, then I don't think it's worth it (It
totally depends on what you want/need the game to do, of course).  A 2D
physics model seems more flexible, and can be implemented pretty easily.

Well, as I haven't really done anything complex with platformers, and my
platform is an AMD 1800, It's not really an issue.  I just cap the
framerate at 40fps, similar to what's done in the chimp example.

Well, the first thing I'd try is to detect a collision, then do a quick
check if the charactor is moving in the upward direction, just ignore
the collision.
