I seem to be stuck. The map says there is nothing more to do. I checked the Strat guide & it said I had to use the tweezers to pick up the pen. The problem is the game will not let me interact with the pen. Anyone else have this issue or a way around it?

I am stuck in Magiafuoco's house. I am supposed to pick up the garden gnome's hat out of the glass display after I did cut it open. But I cannot click it to get it. I restarted the game already but I am again stuck at the exact same step.

Where is it? I remember that game! Could you release it here on steam aswell?
