Their Previous game with the blond had the same system as this, also would get naked I believe after some scenes, not sure if there was a third one though, after getting that part shown on the title, just like in this one....
The previous ones before it, Innermost Dungeon had more scenes and more variations from what I know... have all of the Caryo Innermost Dungeon games, and both this game and the previous....
Also have a few others among wich: D.S.E.
So if anyone is interested I could try and upload/re-upload them on upload sites, although I dont have a mediafire account....
