Additional note: implying that you already installed the necessary software, this is one of the few Windows 3.1 games from Frieve that is still decently playable on modern hardware.
Additional notes I should've noted earlier: Despite the copyright date reading 1992, the game wouldn't release until March 1993, as it was only found on Frieve Present Disk 2 (which also released in March 1993). I should also probably change the name "Demon King Fark" to something slightly different in future releases though.
