Happy Blocks (Happy Blocks)
In Happy Blocks, you and I will have to help the yellow blocks change their color and become more cheerful. To do this, you will need to carefully look at the screen. Before you will see green squares and yellow. To change the color of the yellow square, you will need to move the green controls with the keys and touch the ones you need. Then they will change color and you will get points.
