Some indication of how big is the swarm would be appreciated, could be a simple count of how many locusts there is. It would help a lot, because it's somehow difficult to tell how many there are when they are covered by bushes and trees, it would also help to have a clear idea of how much damage a chicken did eating locusts.
I don't know if a competing swarm would be interesting, it might be pretty fun, but I'm not sure either. Testing this could be a great experience, and if you consider it being multiplayer it could expose you to a lot of interesting development knowledge, network development is very challenging but pretty fun.
