TL'DW? It's >1 hour, and would probably be <5 minutes read as an article.

(edit)
Well, got this rather generic description of the game itself out of Gemini at least:

Scanner Sombre is a walking simulator with horror and desolation elements made by Introversion Software, a UK based indie developer. The game centers around exploring caves with a laser gun that shoots in random directions. The laser gun creates a color gradient on the visor to map the contours of the cave and reveal the player’s surroundings.
The caves are shrouded in darkness and the only light comes from the player’s laser gun. The sound design is important to the feeling of isolation as the player can hear their own footsteps and the constant whine of the laser gun. There are also strange apparitions that show up on the visor, adding to the creepy atmosphere.
The player character, Ethan, is trapped in a cave and doomed to relive his journey forever. He descended into the caves to explore ancient ruins but never made it out. The upgrades the player finds throughout the game are actually downgrades that Ethan experiences on his journey downwards.
The story for the game was added after the main development process was finished and some aspects of the storytelling are not well thought out. Scanner Sombre was not a commercial success and Introversion Software did not make another game for seven years.___

I went into this game in VR not knowing it was soft horror and had to stop a little after the tposing dude showing up on the scanner. Watched a speed run after because I needed closure lol.
