### 1/5 — Rubbish

*2026-07-15, version 1.45*

To many adds

### 3/5 — Игра хорошая!

*2026-05-28*

Но очень много рекламы, и есть вопрос, почему в событие Balloon Rise не проходит дальше 28 этапа, а из 35, что делать?

### 5/5 — 沢山やるとネタがなくなり

*2026-05-18*

作る側のセンスが問われる

### 1/5 — Ridiculous Ads

*2026-05-13, version 1.40*

I couldn't get past level 32 due to the amount of ads. Just this one level continuously glitched out due to the ads. I could only play the easy part and when it switched to the "hard" part of the level the ads did not stop. I watched 4 ads and it still would not let me actually play the level.

### 1/5 — Excessive ads

*2026-04-28*

The ads start out feeling reasonable but as you progress in the game they keep getting longer. Then they start showing 2 very long ads in a row. Once I was past level 60, there'd be 4 or more consecutive ads, with each ad lasting several minutes. I'm deleting the game after only two days. You'll be more successful if you rethink your business model.

### 1/5 — Ads

*2026-04-24, version 1.40*

Whenever I watch a ad I always get hit with a double ad. It’s so annoying and makes the game unplayable.

### 1/5 — Uninstalled .. don’t like timed games

*2026-03-20, version 1.39*

I like games at night so I can relax. Being TIMED doesn’t help me relax. 😒

Deleted game.

### 1/5 — Too Many Ada

*2026-03-20, version 1.39*

Game has promise, but ads are distraction from fun. 
Deleting.

### 1/5 — Так много рекламы я еще не видела

*2026-01-28*

Реклама на каждом шагу, до и после каждого уровня. Я все понимаю , но перебор. Интересно как строиться рейтинг в Apple Store, если у этой игры 99,9 отзывов с 1 звездой

### 1/5 — Bait & Switch

*2026-01-15, version 1.36*

They tried to sell the game on the fun Eiffel Tower.
It’s a very discouraging game because you have to sit through hours of ads after a few minutes of play perhaps I never reached that point I deleted the app.

This game gives a strong feeling of frustration and negativity.
