I was jamming for a while, but then the music stopped. Seems it didn't have looping enabled :(
Unfortunate game-breaking bug aside where the map came pre-explored, you had a nice mechanic of stealthily taking out the guards throughout the world. I'm thankful the wizard gave me an extra light source because it's certainly pretty dark at night time!
I would suggest making the health bar a little bit less intrusive in the screen, because it takes up a lot of screen real-estate when moving to the north. And I see there's a score panel, but I don't know if it's really necessary for this kind of game. But that's just my opinion on it.
