I am surprised that it's only been claimed now 😅
I created the link that can be claimed only once and was simply hoping that EGA will claim it before someone else, as there is no functionality to create personal key links. But it seems he didn't notice my message notification or something. So no worries it can't be claimed again.
I "revoked" the key, not sure if it will unlink from you, but if you want to pay me anyways you can simply donate here: https://musnik.itch.io/donate-me
Thanks for your support!
