The game is great animated and underlaid with a nice background music. The controls are fairly simple: Courli the tennis ball moves up and down independently, it basically controls the ball only to the right or left. But a bit of skill is in demand especially in increasing difficulty.
The app requires fortunately only the absolute minimum of access permissions. Settings, there is little, you can turn on and off only sound and music.
I love the game a lot of fun, it reminds me a little bit to the Platform games of my youth. But I do not mind spending a download and play recommendation. The game is suitable for all ages. Today the app is also available for free.
