The game runs great most of the time anr barely ever lags. But some of the online levels have so much detail that they lag out my tablet a bit but if your playing on high end mobile devices you should be fine. There is endless levels to play including the main ones which the first few are kunduff boring but there is also gauntlets, map packs a lot of map packs, so many online levels and a bunch more. The game also looks great too.
