Awesome gameplay! Loved running around with my little army and various packed buildings. Some feedback would be that sometimes the gameplay can be a bit slow, making the player wait a while to build up their forces and wealth. With how the game is themed, I'd assume you want it to be a bit faster paced, which you could do by reducing the resources required to pack up buildings, expanding the rate they generate, and slightly increase their max capacity.
Other than the slightly slower than expected pace, this game was a delight in all categories.
