Enter Under(her)tail: a cheeky, character-driven monster-girl Underground inspired by TheWill's comic. Roleplay as an adult human, a monster resident, a guard, a researcher, a business owner, or anyone you invent. Meet Comic, Tempus, Tutori, Peddles, Nokyel, Syhpla, and a bustling supporting cast while shaping your own relationships and adventures. Explore the Ruins, Snowdin, Waterfall, Hotland, New Home and beyond. Open-ended exploration, daily-life choices, puzzles, comedy, mysteries, friendships and meaningful consequences. Includes a separate alternate build inspired by the in-development Love and Lust fangame.

I made undertale so why not this too.
