Really nice game, I especially enjoyed the spooky sound effect.
Controls and everything felt pretty intuitive and the layout of the graveyard was interesting enough to not become overly repetitive while searching around for the items.
The only issue I had was with using the shovel, the hint bubble thing was above a cat/rat and I kept trying to run into it at different angles and hitting space and clicking on it with the mouse, I eventually just started bumping into everything in that area and found where I was actually supposed to use the shovel. Not a deal breaker, but could be a little more clear there.
Anyways, really great entry, especially for what seems to be a first jam completion.
