Weird, I am pretty much sure I downloaded it from your site (I was also quite surprised that it was already here, but I even saw the regualr "donate - name your own price" tag that I am seeing on your other games.
The question - is there arny other way to support you (and get access to that particual game) than Patreon? I don't mind making one or two bigger donation, but patreon just isn't my thing.
