Rating video games I've played/I'm playing: I Have No Mouth And I Must Scream

I just have finished the I Have No Mouth And I Must Scream, a point-and-click horror video game based on the book with the same title. The video game includes more lore to the book, so I really reccomend you reading the book before playing the video game (you can find it for free in pdf).

The video game centers its story in five characters who have been living in the insides of the master computer AM, suffering a horrible hell for 109 years by constructing metaphorical adventures based on each character's fatal flaws. You'll have to interact with the main characters to explore their past, traumas and conflicts in various scenarios.

Personally, I give it a 8.5/10 because for me the gameplay is very specific but the story is very enjoyable as a horror video game. I'm hoping this game gets more popular because I think it's an underrated video game.
