itch.io

Right, but what you said was well after I already bought the thing. I bought what I could afford at the time. I even said in the first post that I had already spent the $10.

I don't think I'm understanding. So I spent $10. I have that version. If in the future I want to upgrade to deluxe, do I go to downloads, click contribute +$10 and get brought up to the $20 tier? Or do I have to spend $20 for that version? meaning I would have paid $30 total for the highest tier. I'm not sure how itch.io works.

If I spent $10 to get the game and I want to upgrade to deluxe version, do I just have to contribute $10 or do I need to buy it again at the $20 price? TIA.
