If true, I think this might have rocked from a immersion perspective but people unfamiliar with the developer's prior work expecting more might be pretty disappointed, especially considering they already did a horror bent Blade Runner essentially pretty superbly with Rutger Hauer in Observer, imagine Alien Isolation but with more rudimentary artificial intelligence and no means of fighting back whatsoever just stealth.
That's Bloober Team's definition "survival horror" without exception, with puzzles, and reality warping in-between.
Apart from a major shake up to their formula I do not see how middle ages fits in at all.
