I've been playing this game for years. Recently, for the first time, it prompted to "update" Now I'm seriously considering uninstalling it. The game offers "challenges" from time to time before the upgrade. After the upgrade, I am being bombarded with "challenges" simultaneously, back to back, constantly! Multiple challenges ALL THE TIME! It's incredibly annoying. The "icons" take up a 3rd of my screen! PLEASE make it so if you don't want to do the challenge, it goes away completely.

As always, this free game started off great but soon turned into a slow, boring disappointment. It would be nice if they had more instructions on how to get coins and keys, anyone can figure out the basics. After everything is bought once, you'll need gold coins to purchase any addition, which, of course, is hard to get, or you can buy them with real money. I was looking for a nice game to play in my downtime to relax, but it just gets frustrating. If things don't pick up, it's unsubscribe time!

Optional ad experience rips you off. you can choose to speed certain things up in the game by watching an ad, great idea, really! However, after you spend the forced 30 seconds of watching the ad, you dont receive the speed up as promised. Great idea, terrible execution. also, no place to submit a support ticket. Wouldn't recommend.
