Hmm... I sorta liked it, although it got a bit boring after a while.
Gave sound a 5 (just as with Orbital) because I don't have any sound here.
When i have been reading "Ants",I thought it was a kind of building game....
This provided me with a little bit of enjoyment. Squishing the ants was kinda fun with the green goo when you kill them.Maybe you should add some music and different variations of "squish" sounds. Keep improving it!
