Good work
Innovative concept for a game. Clean up the grammar in the instructions and it'll be great.

Decent Collection Variant
It got boring very quickly since you didn't see your square change much. The concept is cool enough, but you might want to think about using some type of points instead of pixels, and shrink/grow the balls (instead of the square) based on that. You might want to also add some effects beyond fade out for anything you collect. I'd also like to see some other powerup types, like maybe one that lets you change shapes, or one that increases the size of certain dots.
Basically said, there's many places this type of game could go. You should take more advantage of some of those potentials.
Well Done
I enjoyed the game. The graphics were simple but well done, although the in-game font was hard to read. I liked the soundtrack as well, and having multiple goals for the player to choose from is rarely a bad thing. I also liked the way the game balanced itself; as you get smaller it becomes much easier to avoid the grey dots while trying for a high size score makes it a serious challenge to dodge them and continue growing.
