Well done on this definitely quality work

I really would recommend this for kids so they can estimule their creativity and understand colours.
The one thing bad for me it's the lag. I mean, if you just cloud make a graphic selection or a key command to change graphics (such as Ctrl + G or Ctrl + 1, Ctrl + 2 and Ctrl + 3 (1 for Low, 2 for Medium, and 3 for High), I'd be so pleased.
By the way, how I said, the game is really recommended for kids of age 4 - 8. (in this case, me!)

-Things to improve---
Add an little colour-the-screen option, only warning you that this colour-the-screen don't need to paint circulated black areas.
Add an graphic selection menu (as I mentioned above)

-Blamming---
Actually nothing to blam in this game.
It's really fun and creative.

-Protect---
Actually I would ask if you, Newgrounds, cloud keep everything of this game.
Please don't let it be on the red section, as I call, the 'Way of Death'.

-Rating---
Actually I would rate it 5 for stars, 10 for note and (A) for letter.

-Extras---
Favorite, favorite, favorite.

This is pretty okay...
