I love that game, it's realy cool when u have your very own world to burn.
But bigger map would be great, multiple map-saves too. And something to stop virus, i mean: my brilliants ants are brillians and they want to hide themself from virus, they bulid glass shelter, they are all dead. Pretty sad, don't u think?
Ok, it's not best game to be honest, but it's realy nice start! With better graphic, bigger map, diffrent levels (box etc.) and changeable hard value it can be pretty nice.
