Hello - it's not saving cookies. This is Chrome on Windows (I get the same in IE on Windows):
> save game1
Game saved to cookie GAME1.
Type RESTORE GAME1 to carry on from this point.
> restore game1
Cookie GAME1 not found, sorry.
(Type DIR to see a list of cookies.)
No cookies found.
I can see some itch.io cookies in Chrome settings.
Thanks for any ideas! Love the game!
**EDIT Save/restore seems to work fine in Portcullis and The Xylophoniad.
