Well, all I know is, how can he give updates to us purchasers who would get them "free" on Itch, because we paid, when others who didn't buy it could also get them? It would need your order number entered first, or something, and I don't know if Itch can even do that!? It's quite a quandary! I wish I could remember which AVN, but there was definitely one that if you paid for it on Itch, you just needed to send the purchase receipt to the dev at a Gmail address, and he emailed a Steam key back. So it can be done.
