I think the problem is itch.io only looks at downloads on a "per transaction" basis. If I go into my purchased tab for example, I have Lovecraft locker showing up on two different occasions. One for the 9.99 purchase, and another for the 24.99 purchase. but if I go to the page with the 9.99 purchase, I'll only have the downloads for up to the 9.99 options. I'm fairly certain that this will happen the same way. I already paid the 9.99 for the full version of Next Applicant, and now if I want the Deluxe one I need to pay 24.99 on top of it, because it doesn't seem that Itch.io actually has an option to upgrade previous purchases. I'd hate to bother you every time there's a new update for the game, because ultimately that's how it'd end up being. I know your team puts out quite a lot of updates so I can tell that will start getting rather inconvenient.

I guess, is there a way to possibly send proof of my purchase, get a refund for the 9.99 and buy the 24.99?
