This was really fun! I really like the aspect of units having to be villagers that you train and not just being able to magically get a population from the barracks. I like the intro and it's a really nice touch being able to skip it for the next playthroughs!
I would love to be able to use WASD to move the camera and automatically close the currently selected building info by clicking off of it instead of having to use the X.
I also think showing the villages capacity and current production rate of the different building on the little UI panel would be a nice touch!
