From 5 to 0 stars. It used to be a fun and challenging game for a collector game and how everything was before was perfect but with this new update it requires you to have so many more resources that it just feels like a ploy for money. It possible could not be but with how it feels for me it just feels like they're trying to get you to pay them more money.

I honestly don't know why it's take over 2 years to rate this game. Games should be rated only if there is a game breaking bug, or you have several days played to give an honest review. So no game breaking bugs, and 2 years later I'm still here. My toddler loves to crack open power eggs with me in hopes of finding the "Cat" (Kinsley) and my wife now has a daily routine to make sure i get my daily egg. I have only kept 2 other apps on my phone this long, but this one officially beat them out.

Recent update got rid of cash, which could be used to add luck sauce to the minigames to find rarer eggs more easily. That can now only be done with gems which is a significantly slower process, and means getting rare eggs is going to be way less easy now. Game is still an okay enough time killer, but half the point of the game is the minigames which are worse to play now. So if your recent update was meant to make the game less fun, then good job I guess?
