Update: I'm a maroon. Running this game requires using DosBox and the he12.exe Hugo interpreter, as well as the game file. (Thanks to Roody Yogurt for the help!)
I like the sparse yet atmospheric text, the apparent gimmick, and yet...it's a demo game, and it has defeated me.
As of this writing in December 2022, this game won't run in the 3 terps I tried it in: Hugor, Gargoyle, and Spatterlight.
