### 3/5 — Extra torpedoes

*2022-02-07*

When running out of torpedoes, the app give you the option of watching an ad to get more torpedoes.  However, after watching the ad, it changes to a highly ornate page which is locked.  You cannot play any further and you don’t get the torpedoes it has promised.  iPad air

### 4/5 — Close but needs tweaks.

*2021-01-30*

I have been enjoying the challenge BUT 
1) To easy to be detected. I spend way to much time moving around or running silent before damaged from destroyers. 
2) At 100 meters running silent BEFORE DETECTED has no affect. Always get detected. 
3) 100% ducted because damaged should be enabled after certain amount of damage. And options to disable whatever is damaged should should have and option to enable repairs. 

It’s just to hard to evade once detected. I can evade and lose detection without damage - at 100 meters for a short period. But it’s to easy and quick to get detected again. 
Seem very one sided. 
Also, the ability to find warmer water to deflect sonar is missing.

### 2/5 — 画面が見切れている

*2020-06-11, version 3.0*

iPhoneXです。操作が難しく四苦八苦しております。画面が中央部分しか表示されていないと思われるので改善頂ければ幸いです。

### 2/5 — Still serious bugs.

*2019-09-02*

You can now kill the second destroyer as they fixed one bug, but if you elect to earn extra torpedoes the app gets stuck on the page telling you the torpedos have been delivered but won’t close to return to game play. As a result it’s still not worth getting to the second battle. Shame because it ruins the game and also makes the monetisation feature pointless for the developer.

**Developer response:** Thanks for your feedback! I found the destroyer's bug. We revised it in V3. And we add a new stage for One-on-one submarine battle. Happy if you would try this app again.

### 3/5 — 操作しづらい

*2019-08-04, version 3.0*

すみません操作しづらいですね… 
あとはまあまあいいんですが次はドイツのUボートの方を作って欲しいですね！

### 1/5 — Rubbish

*2019-07-12*

No chance your detected before you can even get a shot what sub commander would have is boat above water

### 3/5 — 緊急補給のあと復帰できない

*2019-06-11, version 3.0*

このゲームの初期の頃にプレイしたことがありますが、当時よりも格段にプレイしやすく、面白くなったと思います。
例の駆逐艦はちゃんと撃沈できるようになったようですが、残雷数ゼロで「緊急補給」の宣伝を見たあと、ゲームに復帰できません。再現性あり。iPad 第6世代です。これはバグではなかろうか？と。
なので、「緊急補給」の宣伝ビデオを見るのはやめました。
あと、水平方向の操舵がしづらいです。
他の潜水艦ゲームで、舵輪で操舵するものがありますが、そのほうがやり易いです。
もう一点。ほかの方もおっしゃっていますが、後進が出来た方が良いと思います。現状、敵艦との距離を確保したいときに、低速にするか、停止するしかありません。後進が出来れば、面白みが増すかな、と思いますが。。。

### 2/5 — Software up date needed

*2018-06-18*

It’s a fun game however after watching ads you are supposed to increase your number of torpedoes- game locks after watching ads - needs a fix

### 5/5 — フリーズします。

*2018-05-12, version 3.0*

戦闘中魚雷が無くなり広告見ましたが、フリーズして戦闘を再開できません。
改善をお願いします。

### 3/5 — 当たりません

*2018-05-01, version 3.0*

ステージ2の駆逐艦は1隻にしか魚雷が命中しません。設定なのかバグなのか？
後進ができるといいかも
爆雷が強すぎます。この時代の駆逐艦はまとめて爆雷を発射できないと思うのですが

更新ありがとうございます。
ただ、ＣＭ視聴後の魚雷補充が上手くされません。
画面がフリーズします。
確認お願いします。
