Controlling my little swarm is fun, and the pickups being for individuals is interesting because it hurts more when you lose your overpowered frontline bug. I got to around 80 rooms on my best attempt and never found the nest, how far away is the best and how big is the map? From the scrollbars on the map screen it seems scarily huge.
The mouth hazard made me laugh. I saw it and hovered over and got no info so I walked my little guys over the top and it ate one. Made me laugh - it was very obvious in hindsight.
