✦ AI summary

Players appreciate the game's cute aesthetic, relaxing cozy atmosphere, and fun breeding mechanics for collecting new fish varieties, making it a solid casual time-killer. However, significant technical issues plague the experience, including multi-monitor compatibility problems, poor graphics optimization, and poor UI/UX design, while the Steam Deck version is reportedly unplayable and progression involves excessive grinding that frustrates some players.

Unplayable, constant issues on multi screen setup. Visualy very poor, resolution is all over the place.

Some of the gameplay is a little confusing, and the ux/ui isn't great. Would look at something else like chillquarium. Finished? Gave up. Steam Achievements? A lot of grinding. Steam Deck? Don't try this! Rating? 4.5/10 (.5 because the fish are cute). My curator page: https://store.steampowered.com/curator/45865425-CozyAriGames/ Full videos on Youtube.

Fun Game. Knows their audience. Fish dope. Decorations dope. Really fun to breed two different types of fish together to get entirely new ones. 9/10. Would be 10/10 if prehistoric animals were here.

The game is simple, yet super fun! I’d recommend it to anyone looking for a chill way to pass the time or take a short break from focusing. I loved it! It’s the kind of game that’s easy to pick up and enjoy anytime.
