Nice thing you have here. Seeing the X,Y coordinates in the top definitely gives me a pleasant jam feel. I do that sort of thing myself a lot. After reading instructions and learning I can dig, I was pleased to make some progress. I made it to a minigame. I guess I solved it easily but wasn't sure what was going on there for a bit. It will take a deliberate attempt to try and solve a level/game in order for me to understand more about what is going on here. I also liked the flipped character for left and right movement.
Ahh, I found out what its about. Digging and finding the bones, bringing the bones back to the different people and things it seems. A nice adventure that surely could occupy some time. Minigames are a nice touch.
