I actually thought this game wasn't possible to complete at one point, but I reached the "Game Over...For Now" screen. What would be helpful is if you disclose the total number of levels in this game whether you put it in the description or in the game or wherever. This does have a puzzle feel, but at certain points of the game, my hand-eye cordination is a very important factor to completing some levels, so therefore I don't think it only fits in the "puzzles-other" genre. It's very laggy at certain points, but then again maybe you did that on purpose for the sake of challenge of this game.
I like the concept of guiding a random grey rectangle through a maze to get to a green safe zone before it gets smothered by red circles that grow larger and larger by the second. I know that as of typing this, this game is now under the latest category, but I don't see a place for this game in Newgrounds until it gets cleaned up a little bit.

I can't wait to see the overhaul! Besides "Puzzle's-Other", I think that "Action-Other" and "Adventure-Other" would be appropriate for adding in to the Genre section.
I wish you good luck with overhauling this game!
