Sure, it's fun. But the ads are getting unbearable. Some of the ads you can't even skip or exit out of. Others literally leave you on a black screen, where of course you can't exit out. When you press your screen during the complete blackness, it doesn't even take you to the play store to download so it's just a big waste of time. You basically have to watch an ad to improve at anything in this game so money is almost useless. Overall, it's irritating but still somewhat fun.

Yes, this is just like those games you see ads for all the time. It's okay, but has so many ads itself. You see an ad between each level, you need to see an ad to double your money, an ad to get new items, an ad to see unlock new areas. It's non stop and the game costs $2.99 to get ad free. The game is worth .99 at best. There's no sound and it's quite repetitive.

Surprisingly addicting for a game that's mostly ads (can't use airplane mode). Ads required after each game, ads to get bonus coins, and ads to not lose your achievement award. Then multiple ads to open up EVERY sales table, ads for every possible aesthetic, and ads to play the summer level. I'm tired of watching ads for every tiny thing! It doesn't tell you WHY you're upgrading with ads, what any add-on is worth, to boost your score. Also, the doors need to be more visible.
