Sounds good!
In case if they can't help, just text me directly on Discord with the email you used. I think it'll be faster this way.
Dear Boring Games
It's all sorted! Itch.io support have freed up the Steam Key and corrected their records on both this and four of the other titles I have purchased previously purchased on itch.io.
Thanks for your close attention and my apologies once again for bothering you. I very much look forward to enjoying your masterpiece on Steam and, of course, contributing a positive review in support of the cause.
Grateful thanks and very best wishes for the further success of this and future titles.
Falco
