### 5/5 — Weird, highly recommend

*2026-08-05, version 1.0.12*

Downloaded this six years ago, made a little progress, and then forgot about it. Reopened it last week and more than tripled my progress. I had to figure out how the game works on my own because if there are any instructions, they only show up in the tutorial and then never again (it was pretty easy to figure out again though). I have so many little freaks in my aquarium tank now and I’m having a great time. Sometimes I get a notification that a new creature is on my desk and it’s not there even if I open the notification immediately, but it doesn’t bother me because I know it’ll come up again and I’m not in a hurry to finish the game. I love my tiny freaks and their weird activities.

### 5/5 — I actually love this game so much

*2026-06-07, version 1.0.12*

I was looking for a new game for my iPad and honestly didn’t have high hopes for this one but boy was I wrong. I find myself checking on my aquarium multiple times a day and working towards new goals.

### 5/5 — Very…. Very… Important…

*2026-05-27, version 1.0.12*

This is an EXTREMELY, VERY, BIG and important game! it is something very special and magic and interesting. please continue to add to this.

We request one specific thing please, if you could add multiplayer, even simple things like trading with your friends. This would be so fun and good. Please consider adding this. It would mean a lot. 

Thank you for this game! it is so good :-)

### 5/5 — Good

*2026-04-22, version 1.0.12*

It’s very fun

### 5/5 — 宝箱が出てきません

*2026-04-21, version 1.0.12*

宝箱が1つも出てきません、改善お願いします

### 4/5 — 新種がどこかわからない

*2026-04-07, version 1.0.12*

新種が見つけづらすぎて少し困っています。シュール生物は小さいうえに強調もされないので、通知が来ても発見できず諦めることがしばしばあります。(夜になったら光るなど)改善してほしいです。それ以外はとても良いゲームです！

### 3/5 — 改善求む！

*2026-03-27*

いつも楽しませてもらっています。
しかし、不具合が多いので改善してほしいです。

不具合↓

・宝箱が表示されない・表示されても動画が見られない。

・クリスタル？が貰える広告のボタンが、動画読み込み中となっており、何日経ってもそのままで動画が見られない！

→これではデイリーミッションもクリアできません！改善してほしいです！お願いいたします！
