This is certainly a fun take on the whole "swap-'n-match" genre. (Speaking of which, I'm still hooked on Puzzle Quest 2.) A no nonsense puzzle battler that's short-'n-sweet, but has enough oomph to it to have you hooked until you've beaten it.
BTW, did anyone else here rage finish the final boss on their first playthrough? I managed to do just that after getting a couple of straight 5s-in-a-row. (The latter match being rage tiles.) Epic way to finish it off! =D
Wow... the collision physics are simply TERRIBLE. There's no way you can stop a speeding train THAT FAST with a simple car! (And something needs to be done about the 2nd challenge on lv.33. It's borderline impossible!)
