[PC] Call of Cthulhu: Shadow of the Comet (1993)

How:
Read about it on Hardcoregaming101, bought it on GOG during a winter sale.
Pros: 
- Cool creepy atmosphere and story
- Some nice puzzles
- Very nice graphics
Cons
- Spooky but very repetitive music
- Unintuitive interface, sometimes you must Use items, sometimes you just need to have them in your hands in the right place at the right time
- Easy to lose bearings in town, and understand which locations are accessible
- Slow dialogues
- Possible dead-ends
- Too much trial-and-error towards the end

The game comes with a separate mini-game called "Lovecraft Museum".
