This is great from a technical and artistic perspective. But for me personally, the visual style ruined a great game. I love detective/deduction games. I'm listing some of my all-time favorites in this genre. I'd love to finish Obra Dinn, but god it just makes my eyes hurt so much.
The Case of the Golden Idol
Chants of Sennaar
Her Story
IMMORTALITY
The Painscreek Killings
The Roottrees are Dead
Type Help
Chants of Sennaar is my absolute favourite and I also really enjoyed The Case of The Golden Idol.
I haven't found anything close to scratching that Chants of Sennaar itch so far but I will check out the other games you mentioned as I haven't played any of them.
I also loved the conceit of the Obra Dinn but the visual style made me feel physically ill to the point I couldn't continue with the game. I'm useless with any first person POV stuff in general though.
I really liked the unique style.
Golden Idol and Chants of Senaar are incredible as well though.
I'll throw Heaven's Vault in there as well.
Have you at least played with the other color schemes?
Outer Wilds is the best in class for this genre, IMO.
