I might be wrong bout I don't think you can give them money, because they don't own the images so they can't monetize the game. But as a1fox3 said, check the discord
IIRC, they have/had a patreon for a game they were going to develop, but the only release for it was a demo/proof of concept. It might still be up, but kinda doubt this, as there has been no progress on that front at all.how can i support developers? HS is one of my favorites h game mostly because is has preggo as a main feature, but i cant find any patreon or similar. im really exited about the next update
