This game drains my phone battery even plugged in. After playing for a while my phone will lose its network connection. First, I tried restarting my phone but that didn't help so I used a different app for a while and didn't have the same problems so I reinstalled the app but my save data was lost so I'm gonna move on to some other game now but I'll definitely try this game again sometime. Also, it would be convenient if the game could remember what tank I used last so I don't have to reselect.
