I’m having problems getting a PunyInform z5 game to run on Parchment using the iplayif link. Everything is displayed up to the first prompt, except for the statusline, and it won’t accept any input. I tried it in Chrome and Firefox, on Windows 10.
PunyInform doesn’t do any weird tricks with input. It’s just a Z-machine read instruction. It doesn’t do any weird statusline stuff either, but maybe I don’t know what Parchment considers weird.
Zork 1 Solid Gold, another z5 game, works fine. It shows the statusline and accepts input.
I have the same problem with z5 READ from ZIL. You can see it, for example, here - Werner's Quest - Details [press the play-on-line, then start the InvisiClues by typing HELP].
