### 4/5 — Please update

*2025-10-20, version 0.6.9*

The game is amazing, beautiful design and everything, but it needs to be updated. The buildings are finished and the puzzles too, so there’s nothing new in the game anymore.

### 1/5 — Deceptive Advertising Ruins the Experience

*2024-11-02, version 0.6.1*

I recently decided to support this game by making an in-app purchase, primarily because I was promised an ad-free experience after the transaction. However, to my great disappointment and frustration, the game is still filled with advertisements at every turn. This not only breaks the promise made during the purchase but also significantly degrades the gameplay experience.

The constant interruptions are frustrating, and it feels like a bait-and-switch tactic from the developers. I feel misled and cheated.

### 2/5 — Тупорылая реклама

*2024-10-27, version 0.6*

После обновления начала вылазить реклама на пол экрана, играть стало невозможно и убрать не тоже не получается потому что нет элементарных крестиков , желание только удалить игру

### 5/5 — Donut Hexa Game

*2024-10-25, version 0.6*

I really like this game, it’s so much fun.😁😁👍❤️❤️

### 2/5 — 廣告一堆

*2024-09-10, version 0.5.8*

原本就一堆廣告了，現在又多出彈跳視窗，遊戲體驗超差，不課金沒辦法玩，直接卸載

### 1/5 — More ads than game.

*2024-06-28, version 0.5.8*

Got an ad before I ever played.   Decided to play “delete the app” instead.

### 1/5 — Annoying ads

*2024-06-24, version 0.5.8*

I know ads is important, but if it occupies half of the screen, it’s too much 😖

### 4/5 — More levels, please!

*2024-06-19, version 0.5.8*

This game is highly addictive! I’ve reached Level 400 and am waiting for more levels.

### 2/5 — Жесть…

*2024-06-01, version 0.5.4*

Дошла до 150 уровня, прохожу миллион раз, дальше уровней нет, в чем дело вообще непонятно..

### 2/5 — Fun but not what’s advertised

*2024-05-10, version 0.5.4*

I enjoy the game but since paying for no-ads I get only three plays and they’re out…not worth it
