In other words, people who already bought the game at full price in Early Access will have to buy it all over again if they want the latest version.

Dude, I want to help you but I can't refund you via itch.io.
Itch protects your identity but the flip side is that we creators don't have access to the actual transactions or the people who made them. Try contacting Itch.io and ask for a refund but if it doesn't work you can mail me and I'll do everything in my power to compensate you, OK?
Perhaps just update it here (still only downloadable for those that have payed), a few weeks after game is complete? It would perhaps be a compromise and keep your paying customers happier? I don't think you will really lose sales, as those that buy every version is probably already at Patreon? Or have bought it again already? And making such a move can increase positive reviews (even for the main game page, as you can review games without owning them) and maybe keep any complainers quiet.. Just an idea, I am in no way any business expert.
