Good but spoiled by two little things.
1) clicking on the ants to give them a skill is incredibly hit and miss. You can click on ants and the game just ignores you. Also, you can choose a skill, go to click on an ant and you find that the game has unclicked the skill! Very frustrating!
2) You are not able to see the whole level at the beginning so when you scroll around to see what is coming next you invariably lose a few ants. You can’t even scroll around when you hit pause. It would also be much more playable if you could zoom out much further so you can see the whole level.
Fix these faults and you would have a terrific game!
