In the late 90's, I played this game as a kid. I never played the full game, but I remember having this on one of these demo discs. The whole environment scared me off, but the strange, dark haunted house feeling along with the sound effects was very interesting during that time. I kept playing it because I was curious what the hell was going on in this game. This demo was pretty bad when you look to the story of it and the combat was terrible, but all I did was just running around passing all these doors and collecting items. There was a mouse you had to feed with some cheese I believe? There was a guy in a dark room keep calling "Hey you, over there" that was creeping me out.

I remember in the end you had to repair a robot, that leads you to the next level. Very strange, but correct me if I'm wrong.
