Its a great game my phone is not lagging but doesn't have extreme graphics.

This game is very ambitious from the devs, tutorials are not great at all, easy to lose track of what to do, I think they picked the wrong graphics style for this type of game, in there current form the graphics and scale of the game are literally destroying your mobile battery, not only that, even flagship phones will get very hot after a short time playing this game, also it's only suitable for flagship mobiles, low/mid end mobiles have no chance to run this smoothly, they should of either using a low poly graphics or a cartoon style this would really help with frame rates and heat issues.

The game is poorly optimized.  The graphics are quite simple, but the game overheats the device a lot.  This is despite the fact that the resolution is the smallest and vsync is disabled
