### 1/5 — Too predictable

*2026-08-23*

Played a few games and the clues are ridiculous. “This person is in row and column.” So lame. Would not recommend.

**Developer response:** Hi, thank you for playing and for sharing your feedback. We are actively working on improving the clues and adding more variety to make the puzzles more challenging and engaging.

### 3/5 — Okay game

*2026-08-21*

Why not more stars?

It’s because the rooms in the puzzles are usually not very realistic. And that takes much of the fun out of the game.

For example, a hallway should look like a hallway. But too often a hallway is just a random geometric shape that’s off to one side.

On edit: 
I really do like the idea of this game. And I tried to get into it. But as I noted earlier, the rooms are just random shapes. It takes all the flavor out of the game.

So with some regret, I reduced my rating by a star.

**Developer response:** Thank you so much for playing and for taking the time to share your feedback! We’re actively working on improving the levels and we'll definitely keep your suggestion in mind for future updates.

### 2/5 — 质量很差的谜题

*2026-08-19*

玩儿过murdoku网站的难度就知道，这个app里的题像是AI批量生成的：即使是最难的题，也每一步几乎就能确定唯一解，没有任何推理的乐趣可言，简单关卡和困难关卡的难度差异仅体现在嫌疑人数量的多少/格子的多少。是不是AI其实看线索/房间设计的质量就知道，很多线索是多余的，房间是没必要的空着的，虽然免费但产品用低质量的产品浪费了我的时间

### 5/5 — 希望可以加入点击的音效和简单的背景音乐

*2026-08-03*

很好玩，关卡也很多，但就是没有音效音乐 玩起来耳朵寂寞🥺强烈建议加入音效！！
还有就是手机号和邮箱都登录不上😭

**Developer response:** 感谢您的游玩和宝贵的反馈！

很高兴您喜欢这款游戏，也感谢您提出关于音效和背景音乐的建议。我们会认真考虑您的意见，并尽量在未来的版本中加入音效和其他声音内容，希望能让游戏体验更加丰富。

再次感谢您的支持，祝您玩得开心！

### 5/5 — J’adore !!!

*2026-07-30*

Très plaisant à jouer

### 4/5 — Good game

*2026-07-21*

I like this game. I’ll give it 3 1/2 stars, rounded up to 4.

Why not 5 stars?

It’s because the rooms in the pictures are usually not very realistic. And that takes some of the fun out of the game.

For example, a hallway should look like a hallway. But too often a hallway is just a random geometric shape.

**Developer response:** Thank you so much for playing and for taking the time to share your feedback! We’re actively working on improving the levels and we'll definitely keep your suggestion in mind for future updates.

### 5/5 — Horrible glitch

*2026-06-23*

I’m doing it correctly but it says it’s wrong I can’t pass the level

**Developer response:** Hi! Sorry for the trouble. Which level is this happening on? Please ensure you're on the latest version of the app, as we constantly release fixes. Thanks for your help!
