You must avoid getting hit by the falling balls. If you get past 1000 points you advance to the next level. You want to beat all 4 levels to win the game. Each level is different and will need a different strategy to win.
Balls will be dropping down from the top. With each drop, more balls will be added from the dark figure above. There are mouths on each side that will eat you if you get to close to the edge.
The music is original and Chinese themed. The idea came from an old Chinese Game called Drop Ball where they used to have people one at a time stand in a circular area dropping circle shaped objects down.
