That is such a bummer. Just make sure you charge an amount at least twice the $7 you're quoting now for when the completed game is released on Itch!!!
Another dev told me of 4,000 downloads, only 12 made a donation If it's the same for this great game, you need to enforce a price for the finished game, in my opinion. Prior to it being finished, I understand, but a complete game, made with your blood, sweat and tears need to show it's quality by having an attached price. Just my six pennyworth! If I love a finished game (only 3 so far... :( ) I pay $20-25, I am very wary of spending money on a non-finished game, as so many never get finished. In fact, some AVN's say you have to pay $15 for a 0.4 version that hasn't seen an update for over a year! Now THAT game should be free! :)
