Something is very wrong with this game. Either the developers are mining with the devices processing power or doing some other stuff with it, or it is very badly written. Either way it is using at least 10 times the ressources it should use. My device is burning. Galaxy on fire 2 for example is a 3d game with fairly good graphics and the battery usage is not even half as much. Also this game is yet another attempt to addict you so you pay.
