If a prompt text when looking at the grave and progress bar would help. Nice fog BTW.
Feel free to try out mine as well!
Thanks for playing I realy enjoyed your game. And ya I wanted make a diging animation and make so have timer for the digging not just click it open. Their is a dirt animation where it gets 5% bigger when looking at it but with the fog it not enough to tell. Things to add if I ever work on it after the jam.
