The game "Fued" now runs on OpenBSD -current with a few manual steps to make it work, hopefully this can be simplified in the future. Note that this game requires the recent lwjgl3 and libgdx ports by /u/thfrw and /u/kmos-ports. Packages might not yet be available for libgdx, but it is in ports. I've currently only tested the itch.io version, but it is also available on Steam for free and should work, but confirmation appreciated.
