Good game, it's pretty similar to paper.io. The ads I find to be fairly nonintrusive which I appreciate, I also enjoy the missions and there are some fun skins. Main complaints are that the controls are a bit difficult, I find it's a bit too easy to kill yourself on the side on an arena, and I'm fairly certain all the other "players" are just bots, which is okay but I feel like they're trying to trick me into thinking they're other real people by having whacky names.

I seldom post reviews for apps. I'm here because I love this game and I think with a few slight improvements the experience can increased. 1, when I die in game I want to be able to get straight back into a game, there's at least a 10second mandatory delay each game which adds up. 2, I'm not that interested in the challenges. I just want to play so i would like the option to turn challenges off as the pop up window when i achieve something is so slow to get rid of. thanks love the game!
