people will always make hacks of it if it gets popular enough ... however to be honest not sure why someone would crack a game unless its actually too hard to get too far.
i liked this game, only personal peeve i had was it was too slow and linear. I know its toy cars, but you could put in some real physics like sliding so you atleast feel like your sliding around the corner rather than simply turning around it.
also the collision was pretty off, i mean cars when almost halfway through each other before they'd actually collide ... i'm guessing that you didn't resize the collision boxes?
and i've noticed that people flipping places, i was almost an entire lap ahead of 2nd placer - but he'd flick between 1st & 2nd.
so something to look into.
and the tracks are just a little but to square, dunno but for a cartoon style racer it just seems a little wrong.
and you may wanna give the illusion of speed because it really does play so-so-so slowly that it makes it seems boring... its alright when your ducking between cars trying to get ahead, but when your in first and on the straights really seems like laps take forever on such a short course.
