The app is visually pleasing and simple to navigate, the gameplay is very good. If you want coins and cosmetic updates etc you have to voluntarily watch ads to receive reward. They also offer a costly subscription plan to get more benefits. No problem, but then why show a irritating banner ad all time? Why show full screen video ads in almost every game? I would have given it 4-5 stars if the ads were not invasive and extremely annoying like this. Hope they would improve the experience.
