I really like this game, however, I would like to see just a few changes. If these little guys are hexes (especially with the 'gravity' comment in the guide), they should fit together more solidly. I understand a string of hexes should be flimsy, but a block of them shouldn't be like driving a bowl of jello.
Also, everything else in the game is made of hexes, so the areas should probably be hexes instead of circles.
Great game 5/5
