I think it is a cool concept but could use some polish. Frustrating when the ant is heading toward the food and turns away, but kind of fun to watch them all run around.

EDIT: after a few prestige cycles the sensing circles were big enough to mostly mitigate the ants going the wrong way. However, it gets tedious and repetitive to re-buy the same upgrades over and over. I know that is a common thing in prestige games but I think it gets old after a few rounds.
