Updating my review for the third time after the dev decided to bait and switch their community. Now there's plans to make the game free, after taking money from early supporters. And what do they get as a reward for spending real money? Instant unlock of the max fish capacity, something you get if you played the game for more then 30 minutes. Sure, the developer here listens when things could be changed, and they get brownie points for that, but they lost it all for this. Taking people's money then switching it up on them is disgusting.
pretty cute, but i wish there was an option to only have it be on the desktop and not always be on top, as i think the idea of the fish being only on the desktop would be really cute, and not always on the screen

fimsh go swim fish happy also wish there wasn't a cap on the max fish you can have
Kept pushing for you to buy the full tank version constantly after getting 25 fishes, otherwise decent desktop tank.
This is so delightful. I love fish. There are many fish on my screen. 25 fish! Some are just fish. Some are different goldfish. Some are zombies. Some have glasses or hats! One of them has a shark onsie. I even got a jellyfish!!!! Very fish. Love Fish
I've only played it a bit so far, and I think it's fun. Especially if you're just looking for something quiet to make your screen a bit more lively. So far, there are some good little customisations to it. Such as controlling how many fish, what their colours are, the size of the tank. Stuff like that. As this is only less than a month old, in terms of the release date, it's still pretty new. I would love to see whether the developer adds more to it later. I'd love to see more tank customisations. And perhaps some other types of underwater creatures would be good, too. Like crabs or lobsters. :D
Me encanto, juego para relajarse o pasar el rato, 8/10
буль буль карасики 25/10
