Very cool Alex. Curious will there be much difference on a 64-bit or multi-core system for your game? (Not that I have a version of windows that'll take advantage of it yet I'm running XP SP1 in my VM currently due to a lack of newer discs) Or will there be a Mac OS X version of your game? Just curious. (and on the look for more great Mac games )

Another curiosity; Have you learned anything new while making this game so far? Is there more you could add to your old platform game tutorial as far as character control is concerned?
