Pretty cool! I'm always in the mood for some old school medieval themes! I like the style you went with for this game! And the music was just right!
The sounds for picking up coins and treasure were very satisfying. I admit, I expected an element of danger, like someone might stop me, so I was a bit surprised to run around and just steal stuff in the end.
Overall, a fun experience and an interesting way to implement the theme! Good job!
