It's the game for the brain indeed. I like the concept used, it is quite original. Level of difficulty perhaps is almost the same with the ice cave puzzle in Pokemon Crystal, except this one requires you to think harder (If you are into getting technical). The sound effect is cute enough and not troubling or excessive. I think I will enjoy playing this game endlessly in the car.
Even though it might be easy to play, I would appreciate it more if developer can display a bit of the tutorial or intro.
All in all, Good Job Developer. :)
