Pros:
* I really like the art!
* The game concept is really good!
Cons:
* It was a bit unclear at first what you needed to do. Maybe add something in the main menu that tells you what to do!

Pros:
A good concept (I think, I'm not really sure what I'm supposed to do)

Cons:
You should add a good explanation to the main menu on how to play the game and what the goal is (and yes I've read the description on newgrounds)
