Giveaway follow-up!

Hi all, quick follow-up about the giveaway - I've picked a winner at random, but I wanted to inform them and check they can accept the prize before I announce it (just in case I've picked someone who isn't in a territory where they can use an Amazon voucher). Unfortunately, I've run into a slight problem in that there's no private messaging system on itch.io (this is the first time I've done this) so I'm struggling to reach them. In any case, I hope to announce the winner soon!
