The basic premise is fantastic and the game does offer plenty of variation and challenges in later levels. The difficulty increases at a steady pace, with more deflectors and coloured beams to manipulate. The game comes loaded with 5 different game packs which gives you 20 or so levels. There are also a number of extra packs that can be downloaded as in-app payments.
It looks like some of the juicer power-ups and levels have been saved for the extra packs. Even so, the basic levels give enough satisfaction and if you're not sure you can always check out the Lite version.
