Jamul
This was pretty good overall - big problems include: useless fences, it doesn't matter whether your grass gets eaten (and you can't die), and it's one of those games where you don't really have a major impact (there's no real way to make less grass get eaten... I bet if you moved much faster, you could have some say in the matter!).
But those aside, it's actually one of the cooler entries. Shopping for weapons is cool. So are triple flamethrowers. And of course combos.
