Really nicely crafted game :) It was nice to have the extra challenge of picking resources. I just wanted my little ants to extend their lair as their numbers grew... maybe start with a smaller anthill (how could one ant build all of that at the start anyway?!)
On a technical note, the layout is not screen sensitive - full screen mode made me lose the leftmost column of goodies! No biggie, but something to fix since I think this game could be developed well into a full offering :)
