彩块对对碰 - 碰撞消除大挑战

This is a puzzle game that can be played by sliding up and down and left and right.
In the game, you only need to slide to make the squares of the same color come together, it's that simple.
Our level designer said that he designed the level, only he can do it with the fewest steps. So he is the best in the world. But I don't think so, I have already exceeded him in several levels. I think you can too! Come and try it.
