I liked the game . Really enjoyed playing bro ... Great work and nice mechanics, i hope it will be more and more fun like this playing your future games . 

cool idea

Sweet game great animation on the eraser

Quite a fun minigame. I do love the mouse character pulling/pushing the level to travel across the screen. The messages of encouragement are nice too. Good job with the bigger shapes that take more hits, adds a level of challenge. I know you said in the description that this was a test for another project but maybe you could add a counter to show either how many rounds are left or your score for destroying the paint. Different colours could have different number of points earned. Good game tho :)

Interesting idea, nice job!
