Ceri here!
Wowza, that's a lot of new content coming~! Occult Mingle looks cool and I'm curious to see what else the plot will entail aside from its' genteral premise. I understand that RoD will have to go on the backburner for OcMin to be completed first. Nonetheless, I know that the final products will be up to your and players' standards!
Anyway, Indie horror game recs because I orbit around them daily (and as someone who's recently become a Silent Hill enthusiast):
Signalis (Survival horror/puzzle PS1-style heavily inspired by Resident Evil (mechanics-wise) and Silent Hill (story, atmosphere and puzzle-wise) with endings tied to your playstyle + a secret conclusion accessible via second playthroughs)
Killer Frequency (Murder-mystery/puzzle/reverse survival horror where you're a radio DJ helping potential victims survive a serial killer over the course of one very fateful night)
The Tartarus Key (Puzzle/adventure PS1-style horror about finding a way out of a Saw-esque booby trapped mansion. Comes with great comedy and atmosphere)
Fear the Spotlight (Survival horror/puzzle PS1-style game about uncovering the truth behind a fire that destroyed a high school's theater building)
Lies of P (Dark fantasy/sci-fi Souls-like RPG that retells The Adventures of Pinocchio in a Belle Epoche world where mechanical puppets powered by strange crystals have become hostile to their human creators. Don't know if anyone in the FF team is into Souls-likes but just thought I'd suggest this anyway. The fandom's hilariously obsessed about the pretty boy automaton protagonist and I say this as someone who's actually in said fandom and has massive amounts of LoP fan art on her blog)
Teleforum (Horror mystery visual novel following a camera man and his colleague interviewing the widow of a recently deceased co-worker regarding the strange circumstances surrounding her husband's death)
Hollow Cocoon (Survival horror/puzzle; inspired by the trifecta of PS2 J-horror cult classics (Kuon, Siren and Fatal Frame))
Reveil (Psychological horror/puzzle; delves into a circus manager searching for his missing wife and daughter through increasingly surreal environments)
Indie games in production/releasing in the near future to wait on for:
Still Wakes The Deep (Spring 2024; survival horror set aboard an oil rig off the coast of Scotland during the mid-1970s)
Hollowbody (Q1-Q2 024; tech noir survival horror inspired by PS2 survival horror classics set in a dystopic near-future Britain)
Post Trauma (Spring 2024; psychological/survival horror that pays due respects to the likes of SH4: The Room where a middle aged train conductor must find a way out of an eerie surreal realm to return to his world)
Bye Sweet Carole (2024; dark fantasy hand drawn/animated puzzle platformer inspired by classic Disney movies and Clock Tower)
Sorry, We're Closed (a la mode games) (2024; A cool, queer homage to PS1 survival horror classics with a funky art direction and a veritable cast of unusual characters to get to know)
Slitterhead (TBD; from the man who gave PS1 players the very first Silent Hill game)
No Return (BlameTech) (TBD; psychological thriller-horror that got influenced from P.T. and Devotion)
Leak (Black Point) (TBD; psychological horror with survival elements that has the distinct premise of a former water-testing facility worker searching for his missing family and why a sinister corporation that recently acquired his former place of occupation may have a major role in the disappearances of his wife and son)
