I agree that it's an ambitious game with not enough time! Maybe if we did it in a month or two it'd be a really decent game. We didn't even have time to add music, even though I did at least one tune for it.
If you didn't see the theme it's because you move all ants at once, but looking back that doesn't work too well with the gameplay; we only did that because otherwise the game would get a bit too complicated for the theme. That'd get removed in a more developed version in the game, though.
