I completed part 2. At the end, when I wrote "give key to Salvatore" it didn't work, but "give key to handyman" worked. Also typing "x key" resulted with "you don't have it with you" but it IS in inventory. It's strange but part 2 can be completed after all.
Thank you, I'll have a look at why the key does not have a description, too.
BTW, I found a way to circumvent the issue, but in the meanwhile, I could find that the problem came from a bug in the z88dk compiler: I could discuss about it in the forum and the issue was very swiftly corrected: https://z88dk.org/forum/viewtopic.php?f=12&t=12036&sid=152214e79554d4caa873a5568a386e89
Great! I wrote a page about the background of the game: http://davbucci.chez-alice.fr/index.php?argument=varie/silk/background.inc You have to insert the passwords of the game to unlock the different paragraphs. If you send me the final password, I'll add you in the hall of fame on my website: http://davbucci.chez-alice.fr/index.php?argument=varie/silk/silk.inc&language=English
No, there is an email address on my home site, just do not send attached files: http://davbucci.chez-alice.fr/index.php?argument=varie/silk/silk.inc (look at the very bottom)
