Game seems great so far! My two cents are:
1: as the game has "restart floor" function, I assume it stores your state as of the start of the floor somewhere. Have that persist past the game session and add a "continue" function to the main menu that calls that same dataset.
2: add an open mouth gag (ring gag is the simplest), potentially entirely replacing the ball gags, so that the goblins don't have to ungag her to use her mouth!
