Lots of ads
This is just another one of those games for if you want to advance you have to watch ads. You earn coins but of course they’re never enough, forcing you to watch ads to get them. Loaded with ads which I know makes the game free. But really, an ad before and after each level, plus running ads at the bottom of the screen, PLUS nag screens asking you to rate the game. I don’t care if you can close the ad in 10 seconds. If you have to watch ads in order to earn boosters, then it’s not a a pay to win game, but rather a watch as to win the game, which is just as bad.
