this is a very interesting game concept!
would you expand this game by adding a female dragon character and perhaps extracting milk from her boobs to sell it as a magical ingredient too?
i would love to see this game or something similar centered after a beautiful dragon girl, as that would be a nice concept to play in a game!
(and hiring kobolds to help you out, as thats a great idea)
i really like your games and your cool character concepts, keep up the good work!
