### 1/5 — イライラする

*2026-01-15*

水槽の画面に行きたいのに、課金の画面から動かないことが多くて面白くない

### 1/5 — ………..

*2025-04-30*

재밌긴 한데 물고기 종류도 너무 없고 요즘 잘 안해요. 좀 더 재밌게 만들어 주시면 저 이 게임만 계속 할 것 같아여근데 레벨이 너무 많이 필요해요.  100 레벨이 넘는.물고기도 있어서 아직6레벨 밖에 안 돼요.그래가지고 요즘은 잘 안합니다. 깔지 마세요.

### 5/5 — 暇な時に！

*2024-01-17*

楽しい！

### 2/5 — 알 언제 낳아요?

*2023-12-05*

ㅅㅂ이거 알 존나안주네

### 1/5 — 重複しており申し訳ございません。

*2023-11-30*

お世話になっております。

バグなのか操作なのかは分かりかねますが、レベルが明らかに下がっています。

言葉崩れますが、普通に考えておかしいです。
こちらは時間を使っています。

お金（ポイント）が絡んでいる以上、対応がなければ、こちらも然るべき対応をさせていただきます。

本社の方にも問い合わせさせていただきます。

### 1/5 — 詐欺アプリです

*2023-11-25*

1500円のパックを購入したのですがアイテムが全く付与されません。何度再起動しても何も貰えず。1度目、電波が悪くて失敗したのかもと思い込んでしまい もう1度課金しましたが 結局それもアイテム付与なし。3000円のお金を取られました。Appleに返金を求めましたがそれも拒否され泣き寝入り。本当に最低です。

### 1/5 — ポイ活

*2023-11-11*

3日でバショウカジキは無理
だまされた

### 3/5 — 課金したのに

*2023-10-20*

追加されてません。対応のほど宜しくお願いします。

### 2/5 — ポイ活で始める方へ

*2023-10-01, version 2.07*

ポイ活でやるなら星1つです。ゲーム画面より広告を見る時間のほうが長くなります。
アクションも無理、パズルも無理という方にはいいかもしれないです。

『バショウカジキの卵を7日間で孵化』のミッションは、普通に生活してる人には無理でしょう。
バショウカジキをアンロックするのにはレベル350必要で、1日あたりレベル50上げないといけない計算です。果てしない量の広告を流し続けるしかありません。スマホのバッテリーへの負荷が半端ないので諦めました。

### 1/5 — ゲームとして全く面白くない

*2023-09-21*

ポイ活でダウンロードしたものの、広告見るだけのゲームでゲーム性が何もない。広告見てお金を貯めて魚をレベルアップすると魚が大きくなり得られるお金も増える。ただその繰り返し。
