✦ AI summary

Players praise the game's cute aesthetics and relaxing atmosphere, with a pleasant soundtrack that makes for enjoyable background entertainment. However, common frustrations include confusing mechanics that aren't well explained, a slow progression to actual idle gameplay requiring constant manual interaction early on, and poor automation systems that force excessive micromanagement; some technical issues like Mac compatibility problems are also reported.

Under the sea! I'm having fun raising fish while I work on stuff. Nice and chill game however I wish it didn't take so long to turn it into an idle game. I have to spawn fish constantly or I'll never unlock anything.

It's a pretty slow paced game, I can't consider it an idle game until you have reached that point: [spoiler]Unlocking "Corals" lets you build corals which generates 5 types of fish[/spoiler] Ideally, the game would allow you to have an idle source of income sooner than later. But it's pretty chill once you get to the point that you can actually idle. Some of the things are hard to understand, like the aqua generator system. I referred to a review by lsdelft to understand some mechanics of the game. Overall if you have time and patience, try out this cute desktop aquarium.

SO cute! BGM is all bangers, and I love watching the little mermaid go around on my screen.
