### 4/5 — Insane Aquarium Feels

*2026-03-13, version 1.1.2*

Highly recommend! I really want to give this 5 stars, because I have been playing this for several months now, even after beating adventure mode. There is a tiny glitch in Zen Mode where fish get stuck in one place indefinitely. If that is fixed, I will update my rating. I also wish there was an update to add more adventure and rush levels, because this game is fun and I’m sad that I don’t have anything left to unlock.

### 1/5 — Fix the match three game it’s got me stuck at level 24

*2025-12-06, version 1.1.2*

The only thing I can find wrong with this game is the match 3 if you fix that I’ll give you a five star rating but until then it’s staying on one

### 5/5 — rất vui

### 5/5 — Bugs

*2025-05-24, version 1.1.2*

Fix bug tiếp điiiiiiiiiiiiiiiiiiiiiiiiiii

### 5/5 — Love Insaniquarium Style

*2025-05-16, version 1.1.2*

I was super pleased to find an insaniquarium style game that tries to be unique in its gameplay features. I like that the game attempts to be different in many ways while honouring what made Insaniquarium such a good game. I see that the alternative gamemodes state “more coming soon”, but I primarily play this for the standard adventure mode, so I hope to see more content related to that going forward.

### 5/5 — Nostalgic

*2025-04-18, version 1.1.2*

Reminds me of insaniquarium I wish they had a free play mode also
