Nice game. The only bad part is he fact that all needs and produces money, means that it's just a waiting game, you don't need to think which much in which order to do them. Perhaps adding some material type would add more depth to the game. Also at the beginning it was also not clear to me what the two textboxes below the description meant, since it doesn't distinguish between what you have already, and what you get with upgrade.
My favorite part are the graphics and the whole transitions and animations. Together with the music makes a nice scene.
