You could get people to send you their emails (if they paid for the game already) and then give them a Steam/GOG key for free? The only other way (maybe not possible) is to refund their money, so they can buy it on Steam/GOG? As I paid for the game nearly a year ago, I am not going to pay again on Steam. So when do us Itch purchasers get free Steam keys?

This was going to be my question too. I wanted to by from you direct cause I figured steam took such a big cut, but don't want to have to purchase a second time just to get any further updates that might come out. Especially as I was under the impression the game was done and didn't have anything more major coming.
