Actually...u probably accidentally donated...instead of clicking the one with the price tag on it, its happened to lots of ppl lol
I don't think so... Itch even lists me as having "purchased" for $9.99. And even if it is the case, it's pretty unclear, which isn't really a funny accident since there's money involved.
yeah even when you donate itch will still show it in your purchases, I've donated to lots of games and itch shows that I "purchased" it, so that's something that you'd have to take up with itch 0.0
