### 1/5 — ストレスが溜まるゲーム

*2026-07-18*

ゲーム中に挟まる強制広告と、ゾンビに倒されたらスタート地点に戻されるゲーム性がクソ
絶対おすすめしません

### 2/5 — 面白いけど

*2026-01-16*

飛行機を直す材料の最後のオイル？インク？みたいなのが出てこない。マップがアプデされてないのだと思う。

### 2/5 — おも

*2025-12-08*

おもろいよ

### 1/5 — レビューは読んだ方がいいです。

*2025-12-07*

まだ改善されておりません。

### 1/5 — 時間の無駄

*2025-11-26*

他の人も書いてますが、最後の燃料はどこを探しても見つかりません。クリア出来ないようにしているのですか？

### 5/5 — Love the game

*2025-10-24*

Really enjoyed playing this game. I got the plane upgraded, but it’s asking for barrels oil and there’s nowhere to get them. Is there an update coming?

### 5/5 — おもろい

*2025-03-19*

暇つぶしに良い！
地面や木々を浄化する様子が見ていて気持ち良いのと戦闘も手軽で良かった。

### 2/5 — 黒いアイテム(燃料？)が調達できません

*2025-03-17*

ネタバレ注意です。ゾンビゲームなのにまったく怖くなく、ゾンビを倒して生き残るだけでなく大地の浄化も行う必要があるというのは、珍しい設定だと思いました。途中までは楽しめましたが、どうしても黒いアイテム(燃料？)が調達できません。武器等のアップグレード、ミッションクリア、土地の浄化も終え、残すは黒いアイテムだけを入手すればエンディングを迎えられるのではと思っていますが、肝心の黒いアイテムがどこを探しても見つかりません。緑の石を指示された分入手したあとから特に何も指示がないため、今後どのように動けばいいのかも分かりません。また、ときどき元の場所に戻れなかったり、拾った金色の武器を時間内に使っても効果がないときがあったり、バグらしきものが多々見受けられました。黒いアイテムが調達できないのもバグなのか、故意的にそれを入手できないようにしているのか…わたしにはどちらか分かりかねますが、せっかく面白いゲームなのにエンディングを見ることができないのは残念ですし、時間を無駄にしたなという思いが強いです。もし、黒いアイテムが入手できないことがバグでしたら、至急修正していただけますと幸いです。バグが直りましたら評価を上げますし、他のゲームもプレイしたいと思います。よろしくお願いします。
