WOW, I'm the first reviewer! I LOVE this game for 3 reasons (listed below). I remember when a demo of this first launched on Itchio and you could play the demo in browser without certain effects, I had this running for hours and hours, I only stopped because my browser could not handle all the fish. As soon as this launched on Steam I bought it, day one. For the price you're getting a very unique zen calm experience. #1: It's Unique. Tranquil Koi isn't really a clicker type game. You can right click and drop food and feed the Koi fish to make them mature faster but that's not really the point of the game. #2: It teaches and enforces patience. You don't sit there and click. You buy fish, step away, get some work done, and come back to sell the matured fish. #3 The long term feeling of progress as you collect all the hundreds of different Koi fish. And there are hundreds of different fish, all uniquely modeled. ===== Suggestions ===== It needs optimization, I've got 60 fish and water reflections and I'm noticing the game starting to slow down. It might be because the code for all the fish are constantly searching for food. Maybe code their AI so that they only search for food when you drop it, and only the fish closest to the food notices and starts swimming in that direction? Or maybe change their animations to use vertex animation. There's a glitch, I cannot turn off the water and effects. Using the menu to lower them to zero doesn't work, saving and exiting also doesn't work, and doesn't save your settings, but it does save all your progress. Sorting the fish based on how long they will take to mature would be great. I want to see all my active Koi fish in the list with (23 minutes remaining, 12 minutes remaining etc... for each fish) Some of the Koi fish are so beautiful I don't want to sell them. There should be a new feature called "My personal Pond" where you can send your favorite fish instead of selling them, so you can keep them. Add more music. There's a lot of great non-copyrighted calm music all over the internet. You should add it to the game to give more variation to the sound track. Or you can use AI to generate some really amazing nice ambient tracks using Suno.ai. Anyway thank you so much for this game. It's great, affordable, and so relaxing to have running in the background.
im hooked. buy koi...feed koi....grow koi....sell koi. im a billionaire off these fish now. would recommend: ability to rotate decorations moving fish between ponds pond to save certain fish
I was under the impression that it would be a relaxing game about collecting koi fish and being able to buy hundreds of different koi. Well, it wasn't wrong- but every pack costs almost quadruple the amount of the previous pack, and the koi takes hours (3 hours for the base pack koi) to grow up. I don't have the time or the patience to sit and watch koi swim idly while spam clicking the beginner pack in hopes of getting a rare that only generates less than 1 cent per minute. I'd have 50 kois in my pond and only get max a dollar a minute. And that wouldn't be bad if it weren't for the fact that the first pack you can buy is 150$ and then the next is literally 750$. And each koi does have a sell price, but it depends on the koi quality AND rarity. most koi go for barely 4-10$ and even legendary kois only go for max 160. But to GET a legendary you need to spend thousands. It's a VERY slow progressive game. honestly a little stressful for a person fond of collecting things in games. And the koi GROWS offline, but you don't get money offline. It's not a game for me.
the last update has improved things for me visually and I had a bit of fun today with new koi, location changes looking forward to more fun like this original: what you see on the sales images is exactly what you get okay for many but disappointment for me fish are so small that you can't see the details of them while swimming I was hoping for more in terms of quality of images, everything really the interface is fine but a bit confusing I'm waiting for some updates otherwise my koi, which I love irl, will sit idle without me
想法还不错,但是离线鱼不会成长,物价比较贵,需要一直挂着,但运行的时候不那么安静,办公的时候就有点添堵了。启动游戏的时候,音乐总是自动全开,要再关闭一次,但点开菜单调整以后,ui会重叠导致底层成年的鱼一个个在放烟花,”继续游戏“选项点不中,不好点,比较烦。玩过几十款挂机游戏,总的来说因为题材买的这个,但是实际上挂起来感觉一般
why cant i click half the things like the red x. Meaning I have to quit the game everytime I want to exit. I cant click the teal koi button either.Makes it unplayable :(
I'm really enjoying this game, really relaxing!
