Cool concept!
I think my blobs bugged a little because I managed to send 6 blobs to the wilderness despite only having 3 on the left-hand map to start with.
I was waiting to see when they would return, and then realised it's a manual recall button.
When I recalled my "six" blobs back to base, I lost four of them and only had two left. I started breeding and then they were unavailable for dispatch because of the cooldown.
I think the cooldowns between breeding are a tad long!
Overall though, it's a fun idea and the two map split and breeding mechanics are pretty nifty!
