This game wasn't erotic, it simply had a lot of adult content.  The demons didn't act like fake demons in some games, they acted like simply mean beings.  The game instead was a challenge to escape a bad fate in hell and results in you replaying it over and over to find a way through.  The game designer disabled save and the back/forward buttons, making it tedious to get to the end, but thankfully the source code is small and can be searched for the right choices to win.  The in-game charracter who challenges you says after you won:

"There's only two explanations, from where I stand." She raises a finger. "Either you are somehow able to retain your memory across multiple alternate realities where you are damned, thus gathering the names of each demon who has damned you, learning from your numerous failures in order to claim success here"--she raises a second finger--"or, you cheated."

Very interesting game. I love the plot and the endings. The transformations are terrific. Keep it up!!!

The concept is interesting, the writing is very good and the drawings are nice. I gave up trying to answer all the questions. I didn't get all the endings as it would have taken too long for the back and forth to get all the answers.
