In my dungeon dive research I found this potentially hidden gem. Anyone hear of or play it?

Never heard of it before, but Daniel Thurot’s (Space-Biff’s) review makes it sound great in solo play.
Did you pick it up?
I’ve been on the fence. It seems like something i would love. Wondering why it is mostly unknown.
I have a copy, but have not played it in ages. Any chance you are in Seattle?
Did you enjoy it? Surprised it’s not a larger part of the dungeon crawl conversation. Unfortunately im on the east coast.
I think it is a cool idea. Most of the tiles are supplies and there are lots of dead ends and about 5-8 monsters. I have played The Cave and not Sub Terra. I am not sure if it is superseded by more recent tile-placement adventure games.
It is $30 in the BGG Marketplace and can probably be sold off for close to that. The One-Stop-Co-op-Shop video is quite representative of the gameplay. Unknown | Board Game | BoardGameGeek
