Somewhere around 8-10 years ago (around 2008-2010), I downloaded a number of Japanese games and tried to get them working on my machine. One of them, which came to mind recently, I never got working, but it had a number of videos in the game folder that I could read in my video player. All of the times that I remember involved the clockwork/robot girl, who had long hair, pale skin, and a fair light-colored dress, approaching an area with a measured tread that showed no fear or trepidation, only to get mangled by some trap at that location. It looked like computer graphics of the pre-rendered sort (which would make sense for the video files being stored separately).
I don't remember a lot of the specifics, but I think I recall one where she got crushed by a moving wall, and one where she got impaled by spears. In both cases, she seemed unperturbed (which strongly influences my feeling of her as clockwork or a robot), but was eventually disabled by the damage. My memories aren't terribly clear on whether any fluid, gears, or such spilled out, but she cracked on injury, kind of like a doll with plastic skin. I don't recall any success scenarios, but honestly, I only have hazy memories of it. I think I was frustrated by not being able to play it, and deleted it shortly thereafter.
Honestly, given the games I encountered at the time, it might have been an erotic game (there are a lot of those out there, and were the ones most prominent to download), but I don't remember that showing up in any of the videos.
