### 4/5 — love it but......

*2023-05-31*

i love this game but the levels were so short and after 3 levels there were so many ads and i personally did not like that 👎👎😖☹️☹️😭🙄🙄🙄🙅🏻‍♂️🙅🏻‍♀️🤦🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️🙍🏻‍♀️🍑🍑💔💔💔💔♎️

### 5/5 — My Suggestion level for pencil troll

*2022-08-31, version 1.1*

The level would be that the 2 girls from the game not the anime ones would be skiing down a hill and you need to remove the skies from them and when you do that they will roll into a big snowball and pencil will laugh

Please accept it

### 3/5 — Problems

*2022-05-26, version 1.1*

Too many ads even for a free mobile game and music keeps starting again over and over. Other than that pretty decent.
