If you’re reading this, you probably enjoy games full of perverted transmogrification and Satanic naughtiness. Check out Sabbat: it’s a well-written, short and sweet Twine game that’s aimed directly at scratching those itches.

It was EXTREMELY short.
The only naughtiness were eating the soul of some random christian dude and conquering the earth (referred to as the “good end” as you impose communism over a pile of skulls)
“naughtiness” made me expect sex but there isn’t ANY in the game.
