TL;DR: THIS GAME USES GENERATIVE AI FOR ITS ASSETS. THIS INFORMATION IS NOT DISCLOSED. PLEASE REPORT THE GAME FOR MISLEADING MARKETING. While this game is a nice idle game, I cannot recommend it. They use generative AI for many of the assets and do not disclose it. I REPEAT. THEY DO NOT DISCLOSE THAT THEY USE GENERATIVE AI FOR THEIR ASSETS. I CANNOT RECOMMEND A GAME THAT IS MISLEADING AND HIDES THE FACT THAT THEY USE AI SEEMINGLY SO PEOPLE WILL BUY. Do not recommend. I wish i could get a refund for being misled. Do not support game devs who do not put their whole heart and soul into creating a product that they are proud of; devs that will skimp out by using generative AI. I may have 9 hours on the game, but that's because I was unlucky enough to not have noticed the generative AI for a while, and now I can't file for a refund.

A misleading product not diclosing the use of gen AI. Dev seems to be avoiding comments about the use of gen AI, did not found a single reply that directly address the issue of using gen AI.

I kept looking at some of those fish, inconsistent outlines and overly pixelated but not in a way where it can be chalked up to being its style. So, sketched out I checked the reviews and yeah... it makes sense that Gen AI is being used. I'm sad that I didn't notice it sooner (and soon enough to get a refund) and annoyed that it'll drag down my achievement completion in a way but I can't get myself to give this game anymore of my time, it ain't worth it. Shame on the developers =]

Idlequarium is one of those idle games that instantly sinks its hooks in. Building up your aquarium, collecting quirky fish, and upgrading habitats creates a wonderfully relaxing loop that’s easy to fall into. The progression feels smooth, the visuals are cute, and every new unlock adds a little burst of joy. It’s calm, cozy, and surprisingly addictive—perfect for short sessions or long, satisfying idle runs. A delightful aquarium experience.
