if someone else came here thinking that the game was available on Steam, but all what you saw was an Artwork, don't worry. The only issue is that I can't post a link so what you will have to do is search on the browser you use: ApunkaGames Mr. Jones' Graveyard Shift and the first search that yields that's the one that you have to click on. You're welcome!!

Oh! So you too thought that Mr. Jones' Graveyard Shift was available on Steam because the AI when you ask about where to download this game gave you a link that redirects to this Artwork, huh? Or maybe because you didn't want to pay for it on the Big Fish Games page, you thought that you'll have some lucky by searching for it on the internet, but you didn't want to trust in those sketchy websites, right?
Don't worry, I got your back. If you want to play the full version of Mr. Jones' Graveyard Shift here is:
