If a night time interface is implemented I think there should be a few tweets to make things a little more cool.
1. The walls should glow with whatever color they are giving off light to actually see the village
2. Each troop should have its own unique light source be it their attack or clothing.
3. Maybe have random things fly into the village like a UFO and have it abduct one of the little town people
just a a few little gags like this would be neat to see
