The idea of the game is quite nice and also the simple but liquid 3D graphics are great, but it's on my Nexus 7 virtually unplayable and I'll even after 10 attempts no more than Level 2 addition. Reason is the imprecise control. The ball never flies to where one drags him or snaps. That might be different on other devices, but on my Nexus one can only uninstall again disappointed.
