Here is an online player that renders it properly, other players that google finds don’t line up the clues correctly.
I would upload the puzzle file so you could all play it, but the forum prohibits file uploads that aren’t jpg, png, or gif. Suggestions that aren’t shady-ass filesharing sites? Just go with a shady-ass one?
