I like your art style and the music fits well with the scene.
But the player movement is kinda weird, and I think it would be better if you add an interaction key for talking to people.
(So that you won't start a dialogue whenever you collide with people)
The tracking and digging system is interesting, but just like others have mentioned, it's a little bit punishing to restrict the speed of digging.
Anyway, nice work on this game. Keep it up!
