I smell potential!
I don't know what this games gonna be about but I'm liking the looks of the well detailed animation and game physics. I mean for a guinea pig the thing looks just as pudgy as a real one which makes it all the more fun to animate as well as play. The background also seems to be filled with all sorts of cool crap.
I suppose if I could offer constructive criticism is that maybe you should customize some of the controls. Not used tro having shift be the jump button
But yeah I expect to see the fuinished project! Think it'll have medals?
