It's a cool game. Not too fast, easy to play, even without a tutorial. However, if you're goal oriented, don't bother. You'll not get too far ahead unless you want to let go the purse strings pretty early in the game. It's worth it, just for the artwork itself, imho. The game is as slow placed, or not, as you want it; you don't need to spend a dime unless you want to; and you can just wander around collecting eggs and playing with the one koi, or start collecting rarities, whichever you wish.

It's a fairly simple concept: Eat, grow, mate, repeat. I have no problem with that, honestly. The designs are really neat and I adore the patterns on the Koi fish. It's the type of game you would play when waiting for something, a game to only distract you, not play continuously. Overall, I love it and I will give a good rating on the second one as well. Great job!

I find this such a fun app! The graphics are beautiful! It's a simple game, but for some reason I love it! It took me a bit to get the hang of things and it would be nice to have some kind of instructions somewhere. Also, what are the red plants that slow down the koi? I've ascended 4 koi so far to dragons. I've had to put a limit on the time I spend on the app cuz I can easily while away the hours on this. I really hope the developers get the pro version working on androids.

Hi there, thank you for your review! The red plants do slow down your Koi, but do not harm them. It's just a way to make the swimming process a little more involved for the player since they have to watch out for those :) And yes! We are currently working with Google to have ZKPro available for Android players.
