### 2/5 — Good but

*2019-08-29*

Fun game and challenging, but it needs an eraser and it’s hard to draw with your finger on some levels. This game can be touchy to say the least!

### 3/5 — .

*2019-01-03*

If I don’t beat level 45 by tonight, I’m deleting the app! Done! Guess I’m way too stupid for this game.

::Update::

Deleted!

### 1/5 — Worse! Do not update!

*2018-09-28, version 2.6*

I updated the app and realized it's a mistake!! I used to love this game so much, really, I once thought it's the best game ever, but now, with this updated version, it's ruined. No seconds shown, the game levels are all mixed up. When I click on the level it just shows blank screen, with no cat or dog at all!  Please consider a downgrade to the older version.

### 2/5 — Mohamed

広告うざげー

### 1/5 — โฆษณาเยอะมาก เยอะเกินไป

*2018-06-19, version 2.5*

โฆษณาเยอะด่านละโฆษณาเลย เยอะจนรำคาญ

### 3/5 — NICE BUT THE ADS IS ANNOYING

*2018-06-17, version 2.5*

I understand free games normally got ads but you dont have to put the ads after 2games and the cross on top right is not working all the time! Its getting annoying!

### 5/5 — Great game

*2018-05-11*

### 3/5 — Три уровня

*2018-05-06*

Идея хорошая но управление крайне тупое. Для простой игры довольно заторможенная

### 1/5 — Fun but..

*2018-04-19, version 2.1*

Too much ads
