Given that they have V0.7 available on patreon, i think they've abandoned releasing it here

Dunno if they're just doing false advertising, but one site has what they call version 10.2 on it: https://www.gamesofdesire.com/3d/dual-family/

Figured you might want to check it out in case it's a version of the game that isn't supposed to be publicly available yet
