great game apart from the fact that accounts don't exist 🫤. I nearly reached my first prestige in game but then my phone broke and I had to get a new one and when I did, all of my game progress was reset and it has no way of restoring the progress so now I've quit the game. if you don't care about losing all your progress then this is a great game, has very little ads aswell so otherwise it's a GREAT game
