I've found a new 3D first-person single-player narrative horror game in development coming to PS5/PC, currently aiming for 2023.
It has a few well known names involved such as Jessica Curry and William Pugh. Seems to be a team of around 10-15 people.
I suspect its a partnered indie game similar to Kena/Stray, etc as they had a job listing last year mentioning a "major partner", and in a very recent job listing it says they are now fully funded as a Sony PlayStation Partner.
