Paradise Killer PC Game 2020 review:
It’s a detective game that feels a bit suda. This is a visual novel combined with a large open world, puzzles, and detective quest.

Partum Artifex PC Game 2023 review:
This is a 1s person, ambient horror-puzzle game that emphasizes the story to connect the world’s macabre elements with clever puzzles. Research a serial murderer who is just interested in sharing his narrative and his artwork with the world.
