HELL GAME is a web-based porn game, featuring m/m demon porn and transformation into a monster, or more generally pc/unspeakable otherworldly horrors with some dicklike appendages. There's a more detailed index of content on the game's site, here. You begin as a freshly-dead soul in hell, and you have to assemble yourself a body and set out to explore the strange new world you've found yourself in.

Current content is a small playable demo, featuring the basics of the body/transformation system and about a dozen branching encounters with different demons.
