Death tree

This is a puzzle game. You have a brown box, and it's best to put all the colored balls that fall from the sky inside. The brown box is easy to operate, and its movement is controlled by the up, down, left, and right keys to determine the position of the balls and catch them in a timely manner. Will it fall from an unstable place, on the left or right? Do you have the confidence to score high in this game?
