I enjoyed the music a lot!
The treasure hunting mechanics was fine but it would have been just a bit better if there was also an indicator of the exact spot where you need to dig. For me the game started out pretty slow, and like a lot of top down adventure games in jams the map is a bit too big, doesn't have enough points of interest and the character seem very slow to start so it doesn't feel great to walk around. The lack of sound effects also contribute to the problem.
The in-game art is just ok but I quite like the cover art.
