I am loving the demo! For a future demo (or in the full game), I think it would be cool if there were a gallery in the main menu that depicts all of the punishment scenes one accumulates as they play the game.
Have you played Mira Co. Rescue? There's an item in that (lewd) game that allows the player to view all of the scenes that the player collects from the enemies, bosses, and puzzles; it even allows one to view the game over scenes, even if the player didn't lose. Something like that would be wicked!
With that being said, this is really looking great, and I am looking forward to the proper demo; October can't arrive sooner!
