player can use [A]key and [D]key to remove the little guy at the bottom.the guy can climb a block automatic when player move it.the game's goal is collect coins as a much as possible.but all coins be distributed different rows in pool.so player let the guy reach each position by heap up chunks and clear blocks，but if stack is full,game will over.this is same with classic tetris.

use [A][D]key to move role ,use Arrow key and space keyto control chunk fall down.use [M]key turn on/off music.use [N] key turn on/off sound
