Using the sprites in an archeology theme was really creative.
Awesome that you implemented a highscore system, it motivated me to play more and I think I topped the charts (CRN with 80pts)!!
The game has more strategy than I initially thought, the dowsing rod rewards planning. It took me a bit to recognize this, but once I did I was much more engaged.
I would consider adding more information to make runs even less reliant on luck. Maybe add how many artifacts are nearby besides of how far they are? Not sure...
Overall great implementation of a simple concept, congrats!
