The Castle of Zariostro MSX Hz 60

This MSX Game is based on my favourite movie of all time that is Lupin III Castle of Cagliostro. It is in a tie with my second favourite movie of all time Lupin III and the secret of Mamo. This game was fun to play and I love the way the police stand and have a quick smoke. It was fun until I got stuck didn't know were to go next I had to go up but how?
