If that is your question, no i have no problem with paying.
I don't understand itch.io well enough to know what you could do, but I suppose a better version for a price could be a solution I suppose.
(English is not my main language so it was a bit difficult to understand.) Good to know, that's exactly why I might mess up here and there.
or are you completely denyingthis update "sale"? (If I undertand you correctly, no that would be okay in my eyes.)
If I like a game enough, I accept to pay for it, or for a better version.
