Can't find the first dungeon? It unlocks in the "Punishment Room", increasing your Cunning, and going at night.
Thanks for the comment! I'm working on future updates to have more content in the library, mines, forest, and village in general.
Right now, there's only two femboy character (Nuez, and some slaves ). In the future, there will be "futa" characters(with potions and magic) as well. But the game is focused on goblin women.
