You awaken in a wizard's dungeon. You can't quite remember how you got there, or what you're even doing in her tower... Was it to kill her? To rob her blind? Or just to make a delivery? The details of your life are hard to focus on. For good reason.
Dungeon Damsel is a game of mental and physical transformation. Within the game, you have been disconnected from reality. Your body and mind are now in flux, as the universe tries to figure out where you belong.
Eventually, reality will correct itself as best it can. Whatever form you're in, will be the form everyone remembers. Whatever memories you have will be yours to keep, regardless of whether they match everyone else's.
This is a game filled with "bad" endings - some of them truly demeaning, but most of them simply rewriting your old life completely.
Many of the paths will also be sexual. Almost entirely F/F, or self-F, since.
