Hopefully someone can help! It would be great to rediscover these games.
Game #1: I think it was a sci-fi setting, maybe some sort of lab. As the main character (possibly a robot?), you would wake up and start exploring some rooms, but after a certain number of moves you would be “reset” by some sort of scientist/observer NPC. The cycle would continue until you figured out how to break free (by removing some device or avoiding being drugged or something). That’s about all I can remember right now.
Game #2: I’ve got even sparser/weirder details on this one. Pushing some sort of red button. A deluge of water flooding a tube/passageway. Controlling robots remotely. Starting the game as a corpse?
Game #3: There’s some sort of device that everyone is watching you try out. Except for some reason it’s been sabotaged, and you have to go back and figure out what happened/who did it. Maybe it was a time machine? When you’re in the device I believe there’s some sort of note attached to the inside.
I REALLY wish I knew where my old IF collection was right about now!
