Mobile data usage

Hello, I would like to know why tf this game took 400mb of my mobile data in like 5 minutes of playing the game considering I would use 400 mb if I played clash of clans constantly for a whole day. This is unacceptable, app instantly deleted. I just want an answer why this app which is just a garbage version of coc takes up so much data. Wtf

It is OK. The game is downloading high-quality textures in the background.

Are you sure you are not stealing data from our phone I uninstalled it when its consume more then 1gb maybe in 10 min i didnt even notice until my low data warning pops up​:rage::face_with_symbols_over_mouth::face_with_symbols_over_mouth::face_with_symbols_over_mouth::face_with_symbols_over_mouth::face_with_symbols_over_mouth::face_with_symbols_over_mouth::face_with_symbols_over_mouth:
