Galaxy and Stone

Game details:

This game is somehow similar to famous pong or breakout games and you have to keep the stone in the screen as long as you can. 3 sides of the screen are closed and your platform is on the right side. The stone starts moving and after hitting the walls, goes to a direction and you should prevent it from exiting the screen and hit it back at the walls! You will get a score based on how long you were able to hold the ball in the screen. But remember, this game isn’t very easy!
