In the creator's most recent twitter post (1 month ago), there's a gumroad link in which he mentions "starting back up game dev".
I think this is just a creative or not having enough time issue. Game could get abandoned or worked upon again in month or years.
Patreon was deleted too. Not entirely sure what's going on, doesn't feel like they were arrested/copyrighted tho, as this page should've been taken down if so
