One of my first LucasArts games that I got from the GoldGames magazine.
Back then it was the german version, by now I switched to the english one.
I actually didn't play MM1 extensivly, until this day I didn't finish it. DOTT did right what the old LucasFilm games did wrong. It was easily accessible and still maintained that humor which they are famous for.
At some point I knew every aspect of the game by memory. I don't do speed runs, but since you basically can grab all items from the beginning, I was able to complete it within 40 minutes.
First time it was a bit frustrating that I didn't find the professor after he went up the stairs. That said he will appear back in the basement if you complete a certain task. If you have all the necessary items already, you can just go back down and there he is.
