Fun game, however, it's a tough grind for XP, even opening chest require you to play so much, and they purposely allow you to buy it from their shop for a price,and the advertisements are annoying, definitely focusing on pay to play model, and not just that the advertisements on this game that is the big problem. It's how they sell you things while already earning your money from advertisement, I'm uninstalling this, I came from Bloon TD 6 and personally that is much better.
