It is a nice touch how originally there are 6 zerglings coming out and others came in pair.
For anyone who never played Starcraft: zerglings are created in pair, two per egg and the maximum number of eggs are 3. A player who attempts to do a zergling rush wait for the first 3 eggs to be available, hatch them and subsequently make a new pair of zerglings as soon as a new egg is available.
I would have liked Google's implementation more if instead of clicking the little O's to kill them, you get to instead make buildings that produce G's or something to defend. Clicking the O's isn't really starcrafty.
I guess you've never tried to focus fire/snipe banelings that are part of a zerg army moving towards your marine bio force. Accurate clicking is very Starcrafty.
