Apart from the bug after pressing "E" (the upgrade menu, after that it does not allow me to keep on playing as a 3rd Person Shooter), it is very cool. I liked the 3D environmet set, and I laughed when I saw the little guy dancing in the Main Menu.
Please keep on working on this game, it has a good potential (you might add more dwarfs, each one belonging to a class with a particular skill - Guard, Bomber, etc)..., you could also add more enemies and they could attack from a distance, etc, it's just an idea.
Good work.
