I've played for a little over an hour and got past a few levels after 50. The game itself is alright, but it's the ads that make it a 2-star experience. Almost everything that you do in the game requires you to watch an ad beforehand. The game is sneaky about this and makes you have your internet on, so no airplane mode to bypass the bombardment of advertisements. Overall, don't get the game unless you enjoy playing a game in between your ads.

This game is genuinely what is advertised and quite fun, from what I can tell after a few days of playing. My issue is the ads. There is far too many to the point where I will get one at the end of a level just to get one at the beginning of the very next level. It's shallow and leaves much to be desired. Easiest uninstall of my life.

I absolutely HATE this game it's so stupid and quite unfair. For example, to be able to level up AT ALL you have to watch a MINIMUM of 3 ads AND still pay however much money you've earned. It's just really annoying and I promise this game is not worth it
