I like the story idea, I just wish that it would run better and for the existence of sound and animation. Another thing would be to fix the damage system, since you could get hit/touched by enemies and take multiple points of damage, die, or just get hit once. A different issue I had that I thought was funny was that when the farmer walked over one of my eggs, the farmer went flying about 30 meters into the air and got stuck on top of a fence post. Don't know if it was intentional design, but it is definitely gruesome if you think about it (REVENGE!).
I think the lag may be coming from the high rendering/camera expectations from those settings, or maybe because the AI are targeting the player every frame? Idk, I don't even use unreal. :/
A cool idea, and good execution for the limited time.
