Demon's Sword

Demon's Sword (2016): Role-playing (RPG). Developed by Cannibal Cat. Available on PC (Microsoft Windows).

Demon's Sword is a simple and completely unfair dungeon crawler in the vein of Telengard. Your goal is to collect a number of relics in order to defeat the demon Fulad-zereh, including the legendary Shamshir. You may cast spells or summon powerful demon lords for assistance, but at a dire cost to your Purity. Lose too much Purity and you shall join the damned wandering those accursed halls forever...
