Not all mobile games are created equal. Some are fun, others are ok to kill some time and others are just complete garbage and aren’t worth downloading. This one is not worth downloading. You basically tap the button to jump, hold the screen to spin and let go to bounce on trampolines or go down slides and try to get enough spins before you dunk the ball. It sounds like it could be fun, but honestly, it is not. At all.
It isn’t hard, it just isn’t fun. The fact that every two or three levels/ attempts results in an ad make it even worse since each attempt takes about three seconds. This is one game you just should never bother with, best wishes and may the gaming gods bring you glory.
