Lilith's throne is a text-based erotic RPG, in which you travel through a world filled with demons, magic, and lots of sex! Some main features include:

An explorable, randomly-generated map.
Turn-based sex, which gives you a lot of control over how a sex scene plays out.
Randomised, persistent NPCs, who can be fully transformed!
Levelling systems for perks and fetishes. (Currently 30 fetishes, with plans for a lot more!)
Fully transformable bodies, allowing you to turn yourself into all sorts of different races!
A lot (currently 132 items) of clothing for you to customise your character with.
Options to set your personal preferences for NPC furryness, gender, and gender pronouns.
Lots of sex! ^^
Weekly releases! (I update TFGS every fortnight, but my public github and Patreon builds are updated every week.)
