Maybe it's a random itch.io find; maybe it's a minor title from a long forgotten console; maybe it's a dev project your friend asked you to play test. Whatever it is, you think it's neat, and you never see it mentioned anywhere.
Tell us about the game -- what is it? Why is it noteworthy? Do you think it deserves more recognition than it's gotten? Why do you think it's as hidden away as it is?
