I think you should add some sort of leadership upgrade, so that you can control the shape of your flock midflight - at some points in the game i just wish I could make it skinner and longer or broader.
ie. press x to make it longer and c to make it fatter.
Moloch attacked me within 24 hours: after he slaughtered his way through my heavily defended base, his monsters vaporised and I won - poor effort, knocked my 3 start vote down to 2 for that. Either make it so you don't get anhilated or let them win. Be consistent -.-
