[b]Merits:[/b] ▪ It looks pretty ▪ Supports touch screens ▪ You can unlock more variety [b]Flaws:[/b] ▪ Not a game, more of a screensaver ▪ The unlocks feel very similar ▪ Limited pond customisation [b]Verdict:[/b] For the price I paid, I got a decent screensaver. However, the same effect could be achieved with a YouTube video. I feel like the software would need a lot more options to work as a fish tank simulator, which I though it was at first. [b]Rating:[/b] ★★☆☆☆ - Average

[h2] idle game to focus on real life tasks if you love Koi fish [/h2] had to move from [redacted fish game name] after the new update of the game [u] What I liked about the game : [/u] - This game allows me to admire the fish without having to upkeep the tank, just clicking feed once in a while - very realistic graphics of the fish, flowy movements I could see the scale - decor are beautiful and simple, just click - I get the job done with optional rain and zen music in this game, sound design in this game is very well, even when just clicking cursor on the water there is fizzling bubble, I can tell that the game was made with lots of effort and professionalism. [u] what I disliked about the game [/u] - there is only one developer in this game which I'm not sure if it is a blessing or not since [redacted fish game name] got more dev and they kept trying to fix stuff that didn't need fixing until the game lost it's essence. but I am pretty sure that My Koi will remain unchanging, but the con of it is also that there is not much new update to the game, last new thing was the Halloween skull Koi. - the music is repetitive after a while which is understandable, I just …

Game is really realaxing and cool. Nice Koi Fishes. It would be great if developer updates game and adds options like fish breeding and selection so that we can transfer fish from ponds like we want and to organize them.

I'm not sure how much you can call this a game but it is fun. I do wish there were additional features like breeding and even more ponds/pond decorations. Also it's been a bit slower getting to the next size of fish to unlock more types of koi. Despite that it's very relaxing and the fish are very well animated. For those new to the game, the only thing you really have to do is feed fish once a day. They won't die if not fed but I did read somewhere that if it goes on too much it can stunt growth eventually.
