  1. [R2] Cow Evolution 5/5 · US why cow evolution is the best game oat:: its peak
  2. [R3] Cow Evolution 3/5 · US Not enough content: The game is really fun for the first few hours but there is just not enough content it gets insanely repetitive. Would be nice if there was maybe more upgrades or something so you actually had a reason to reset for higher earnings but has it is there’s nothing to do
  3. [R12] Cow Evolution 3/5 · US Disappointing: You eventually get hard locked at only needing diamonds to actually upgrade your abilities and you just have to wait for days to get the currency needed to advance. Great game for the first 1 or 2 days of playing but a waste of time afterwards.
  4. [R14] Cow Evolution 5/5 · US Too much fun 🤩🤩🤩: This game is so good my brother let me try it. It ended up being so addicting
  5. [R1] Cow Evolution 1/5 · US Too many ads: Self explanatory. At least you still get a reward after an ad plays, but they still happen far too frequently (every 5 actions or so)
  6. [R4] Cow Evolution 1/5 · US Way way way To many ads: It seems like there’s an ad every ten seconds🤦‍♂️
  7. [R7] Cow Evolution 2/5 · US Constant ads. Can’t close menus or switch maps without forced ads: Whenever you close a menu or try interacting with things it forces you to watch an ad. I find myself just closing the app every time it happens.
  8. [R9] Cow Evolution 3/5 · US An ad about every 90 seconds: It’s just a ridiculous amount of ads
  9. [R13] Cow Evolution 1/5 · US Can’t even play!: Ok so I see a bunch of reviews that says it’s five stars ⭐️ but when I try to get in the game it kicks me out and I tried like twenty times and still didn’t even work!!
  10. [R21] Cow Evolution 3/5 · US App crashes and cows disappear: Mindless game. I like it for that reason. But the more I’m playing it, the more I notice my high value cows just disappearing. Normally after merge all the way up to level up my Supreme Being. Then when I go the next level down, any remaining cows in that level are gone. That and the app sometimes will run slow or crash. Of course it’s usually when I’m using a pin
  11. [R27] Cow Evolution 3/5 · US Thief.: Game crashes after you buy no ads, cash cow corporation.
  12. [R31] Cow Evolution 1/5 · US Bad: I can’t get in
  13. [R32] Cow Evolution 5/5 · US Simple, cute, well made!: I love this game!! It’s so cute and the art style feels so cozy! All of the cows are just adorable and goofy, I love the music for this game. Easy game for when you just want to relax!!
  14. [R38] Cow Evolution 5/5 · US Birds: Bring the birds back as the evaluation box is annoying to deal with, the birds give chance to earn money the box doesn’t Same for any animal evaluation game where this statement is relevant
  15. [R57] Cow Evolution 3/5 · GB Addictive: I love this game and what happens with many games they become very addictive. It’s an amazing game as you mix cows and great new breeds. I would of 5* the game but the layout on the iPhone XR is bad I creat click on the costumes you can buy for the cows.
  16. [R60] Cow Evolution 3/5 · GB Fun but: The aspect ratio is off half the screen is cut off so you can barely click the options at the bottom of the screen.
  17. [R61] Dragon Evolution 1/5 · US Too many ads: This would be great if there weren’t ads every 3 minutes
  18. [R66] Dragon Evolution 3/5 · US Annoying Updates: I have been playing this game for a few years and I still come back to it fairly often. I really enjoy the main idea of this game, and the designs are super cool. However, I have a few issues with ADS. There are SO many ads, they interrupt ALL the freaking time. And they’re not short ads either, often up to 30 seconds. I really don’t understand why there needs to be such an insan
  19. [R73] Dragon Evolution 1/5 · US loss of progress: It’s a good game and cute but any upgrade purchases you buy with in game money ex. Apple recharge or crate quality keeps resetting after a couple of hours for both Dino’s as well. Doesn’t matter if you spent diamonds to get the next upgrade
  20. [R75] Dragon Evolution 3/5 · US Was fun until it kept crashing.: I’m an avid fan of these types of games. On my old account, I played the goat and cow version religiously. However, this game is often crashing on my new phone now. I haven’t even passed the first God dragon, at most I’m at level 2. I only have ~20 seconds before it freezes visuals. Audio still works to guarantee the game is still working, but it just crashes rep
