Monstergirl Forest

A portal yanks an ordinary guy out of his own world and drops him in a forest that's anything but ordinary, one thick with harpies, lamias, slime girls, and centaurs who all want something different from him. Some see a meal, some see a companion, a few just want to mess with him for fun.

The setup is simple: he's stranded, they're not going anywhere, and he has to figure out who's dangerous and who's just lonely.

Every encounter gives you a choice to fight, run, talk your way out, or lean into whatever's being offered, and those choices decide who warms up to you and who doesn't. Later on a second portal opens into an Elf World with its own residents, though you can always head back to the forest you started in.
