from my understanding you'll keep what you have purchased since your copy of the game is a ticket in your itch library. I think that makes sense to me since I have the ability to give out download keys if I want to.

>I honestly was surprised when I purchased it due to the VAT not being included
this is news to me @w@ but I guess makes sense, itch is an American entity.
