5 stars: Relaxing music and gameplay. You can progress well without paying any money at all and ads are few. They only pop up if you go through the menu occasionally or if you choose to watch them to earn pearls. It is a very nice game to play at the end of the day to unwind.
5 stars: I can remember playing this game on my dads phone when I was bored after begging him to let me go on his phone, so it might be the memories talking but I love this game! It has really good graphics and has a challenging yet easy game play
4 stars: This is a beautiful game! The graphics are stunning and the music and sounds are pleasant. I've taken one star off because gameplay is so redundant. Each new koi goes through EXACTLY the same stages to transform at EXACTLY the same pace - no challenge at all after a few times. I'd give it five stars if they'd mix up the levels, and also be a bit clearer about the purpose of some of the rewards.
3 stars: I love the idea but some animals are really hard to find and the problem is after you get all the eggs its hard to find out where the thing is
2 stars: After playing for a bit, every time I went to see what I needed, I had to watch an ad for five seconds, which got annoying real fast. Whatever relaxation I experienced got ruined each time I had an ad thrown at me. Edit: Yes, I know that devs need to make money and all that. I just don't think irritating the player into spending money is a good way to do that. It's a cute little game othe...
