PapiRiver is a scroll action game.
Mr.Papi (red ball guy) is going down a river.
Tilt your iPhone to left and right to lead him along the river!
If he hits the bank of the river, he is pushed back. The game ends if he goes out of the upper edge of the screen.
Note that you can get more score when he gets closer to the bottom edge of the screen.
This app contains 2 levels - Normal and Fast (locked at first).
