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.

Fun relaxing little game about merging cows. The review would've been a tad bit higher if the game wasn't so bent on forcing ads every few minutes. While it's good that the forced ads give you rewards for watching them, lots of ads forcefully redirects you to the play store, which in turn closes the game and gets you basically nothing in return. Just started playing for less than an hour and the ads were already tedious to deal with. Plus, a lot features are hidden behind ads.

I paid for the ad-free off the cuff so the review is based on that experience. I can't speak to the amount of ads. It's a fun little merger and the design is very cute and fun. Comic sans was a choice. My only complaint is the depth of the game. Unfortunately I'm glued to my phone and I finished all of the achievements within a couple weeks or less.
