I am a professional Unity dev and an indie game dev. On Itch I have a little 10-15 minute horror experience based on a creepy pasta called "The Portraits." I also released a prequel to another game I made called Atama Ikuto where you use your powers to see through the sight of enemies to help avoid their gaze. I also have a free Unity asset pack for a Japanese Ryoukan-style private bath room, feel free to use it.
On Steam, Itch, PlayStation, and Xbox I have a larger, more gameplay-focused stealth horror puzzle game called Atama (it also has a "story mode" for those who don't enjoy stealth, though!).
