Charming, narrow scope which clearly helped it with developing some depth, but sadly completely infected with the forced ad virus. Literally every few seconds you close a menu and you get a forced ad. Forced ads are already immoral and shallow, but pushing them multiple times a minute is just straight-up harrassment. Please somebody talk with the monetization team and explain to them that literally nobody wants to see ads, ever, and that forcing us to see multiple a minute just ruins everything.

Would have been 5 stars if not for the ads breaking the game all the time. Every time I use a Berry an ad pops up and by the time it's finished my Berry effect has worn off. And yesterday I won an achievement worth 10 diamonds and because an ad froze and I had to re open the app I lost them. It's a joke and it makes me angry at the game. I use to be able to play it for hours but now I can't play for more than 30 minutes without an ad making me rage quit.

I was really enjoying the game, but the new update is not good. The opening animation for evolution crates is too long, it should either be made much shorter or made skippable by tapping. Also the speed of crates has been drastically increased while crate quality has been decreased overall. This makes the farm level clog up very quickly and the game becomes rather hectic. I do enjoy the berry mechanic, though the purple berry is op compared to the others.
