In principle, the game design is very interesting. As one of the oldest skill game variants you have as far as possible to slide along narrow paths through space with the ball by skillfully balancing. The control has always been what makes the difficulty.
In this game, nothing really fit together. Starting with the amateurish hunted by Google Translate Description (the English version can be found in Google Play Store) to nonexistent highscore system is the app placed very amateurish. The graphics is rather poor, the control spongy and rather sluggish as too sensitive.
For the game itself: there are 3 difficulty levels ... that's it. There are no options, no level choice and as mentioned no highscores.
Conclusion: this download you can give. Is catchment positive that the app manages with few permissions.
