✦ AI summary

Idlequarium is a functional idle game with solid mechanics like offline progression, customizable tank accessories, and quest systems that appeal to creature collector fans, but it suffers from significant issues including spelling errors, visual inconsistencies, and—most critically—undisclosed use of generative AI for assets, which players find deceptive and have made the game difficult to recommend despite its core gameplay being competent.

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.

Overall Idlequarium feels like a solid creature collector and idler game that allows you to progress collection goals while offline (i.e. fish will grow and mature while you are not physically in-game). There are also interesting features (compared to other simpler idler games) where tank accessories have specialised stats that can be upgraded to increase passive income generated, speed of fish maturity, etc. and quests providing additional income, upgrade materials and tank equipment. The game however lacks that final polish in several aspects including: - Spelling errors (e.g. the congratulatory 'Awsome!' message when discovering new species, maxing out tank accessory upgrades pops up with Chinese characters for "Maximum Level/Upgrade"). - Clicking on the 'Unlock' button for individual fish does not always work and then requires manual selection of all fish in order to unlock makes playing the game annoying at times. - Lacks quality of life updates where opening fish packs becomes mind-numbingly boring when players are ready to collect all rainbow/golden variants of fish species. The process of opening fish packs one by one, followed by manually unlocking automatically locked …

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 =]
