I purchased Misery on itch.io three days ago and have had no luck getting it to run on Linux Mint (I followed the instructions that came with the package). The Misery page says that purchasers would have access to The Augur, so I thought I might go that route instead of beating my head against the Misery wall. I'm not clear on how I would get this access to The Augur as a Misery purchaser however. Guidance please?

Hello, go to https://augur-studios.web.app/ this the upcoming 2.0 version of the augur.  It will detect  your misery purchase when checking ownership.
