### 4/5 — Great game..

*2025-02-18, version 1.0.7*

I gave it 4 stars because it didn’t have a camera or notepad…Otherwise I had fun playing it..Luckily I keep notepads just for this occasion..

👍

### 5/5 — 楽しかったです❣️

*2024-10-29*

穏やかなBGMなので落ち着いてゆっくりplayしましたけど、これって泥棒ですよね（笑） もし慌てて脱出したらと思って…ノーヒントクリアで３エンドを楽しみました。 
しかしながら宝石を採掘したり加工したりする工程は楽しかったです♪ 移動も簡単に出来たので何度も掘りに行ってしまいました⛏️ それに採掘場の中を特殊な灯りで照らした時は下の方にルビーらしきものが有ったりで素晴らしい光景でした。 そんなグラフィックが素晴らしい作品で宝石にピッタリでした。

### 3/5 — 椅子！(笑)

*2024-09-22*

イスの脚を直す作業とか岩石を精錬する作業とか捲れるカーペットとか、その場面にならないと反応しないみたいな事ですかね？前にやったらできないのにある時に急にできるようになる、なんてズルい事が数回あったような？『さっきやった時はならんかったぞ？』と。気のせいならすんません(笑)1回ごとに謎解きが終わって次に何したら良いのかがわからんゲームです(笑)

### 3/5 — さいご

*2024-02-06*

ハート、どう見ても左右対称なのに何故反転？

### 2/5 — jojoma

*2023-06-14*

The last puzzle (the door) was pretty dumb!

### 3/5 — 運命の宝石

*2023-02-08*

むずかった。

### 3/5 — 面白い

*2022-07-17*

ヒントを見ようとすると有料の方しか行けなくなってる。楽しいがそこだけマイナスです

**Developer response:** レビューに気づくのが遅くなり申し訳ありません。広告を見てヒントを得るには、広告削除ボタンの下にある✔を押してください。わかりにくいと思うので、次回Updateの際にはボタンの場所を変更いたします。

### 5/5 — 解きやすかった

*2022-04-15*

ダイヤができるまでの工程をリアルに楽しめました。時間はかかりましたが、ヒントなしでクリアできて嬉しかったです。

### 5/5 — ノーヒントクリア出来ました

*2021-10-24*

わたしにとって、とてもいいレベルの脱出ゲームでした。やっぱりノーヒントクリアすると最高に気持ちいいですね。^ - ^

### 5/5 — Perfect challenge

*2021-07-22*

I have not played this game but I assume it will be as fantastic as the others games that have the perfect challenge.
