hope you can modify the game's ending mechanics, as this is the aspect that can most fundamentally change the nature of the game. If you are defeated by certain enemies, you could add a scenario where 'your team is kidnapped and taken to a certain location.' Then, each member of your team might be raped by slimes/animals/bandits/monsters for a period of time and lose their belongings, returning to a nearby location with lower health. This could later develop into actual kidnapping, with frequent failures leading to more variations, and your members may become corrupted.
