Ok, so it's been out a while, think it had a period on Gamepass too (a while back) but I felt an urge to play it before I really tackled Call of the Elder Gods (which is now on Gamepass).
And its distinctly...... okay.
It's really just one of those 1990s click screen puzzle adventures presented in a first person world - each scene having no more than a handful of puzzles to progress together with story items to read. But it's not too complex, no convoluted combine x with y to do z, so predominantly reading the things that present the clues in your notebook to apply a solution - rotate this, press these in this order etc but some logical steps are needed at times.
What is mostly missing is the compelling narrative - it's all a bit too vague and fragmented and if it wasn't my familiarity with HPL and CoC / Shadow Over Innsmouth, then I'm not too sure it really holds together that well, but is more a fan service for those who already know (inc. the odd document signed by Tillinghast, Dexter-Ward, Pickman etc)
A pleasant enough stroll around, and the occasional swim, 8 hrs and probably about 3/4 of the way though it
