The link to the new page is in the comments of the YouTube video.
The developer's posts indicate the cost required.
Their Patreon is no longer operational.

Ooh where can we find the renewed link. I went and purchased the patreon for the new Under the Witch Gothic game but I’m not good with computers and could not figure out how to play it

Thank you very much for your comment.
The thing is that the previous page of the game creator has been suspended. I have already renewed the link to the new page.

the link doesn't work

Where can I find the game? Only found the first 2 episodes
