When I search though I didn't see it listed. I only see this version :\
Weird, itch.io made a statement about free nsfw games
Somewhere someone said that asked why to them and that they said that they asked to remove the payment option in the game so it would back to be listed. Just cut off the donation options I think.
I told some people to check if GOG accepted those kind of games since they have adult games there few ones furry.
Since sounds all that happened because PayPal, Mastercard, Visa and the other don't accept payment for adult stuff art and told them to remove. I read it somewhere.
The developer of Echoes from Valeth just moved his downloads to a adult service.
