A couple of minor nitpicks: (1) if your game needs to connect to the internet, I would specify why in your description. The first thing that popped when I launched it was Windows firewall blocking network access for the game. (2) Please include some kind of way to close the game if it's going to take over the full screen.
The controls to shrink and grow weren't working for me, but the concept seemed interesting and the environment looked really good!
