I used to play this as a kid with my little sister. She couldn't figure out some of the puzzles but really liked the game. This was aroun 2000/01, sor she was 4/5 and I was 10/11. So I would play the game, while she watched. I don'r remeber too much of the game, just vague parts. I remember an FPS section and that the teacher who is an alien is randomised.
