Through the Fragmentation & other unique games?

Just picked up Through the Fragmentation during the summer steam sale this year, and have only played a small amount so far today, but it's very... interesting so far. I added it to my wishlist a little while ago when looking around on Steam for unique games that are immersive and/or experiential in some way.

It's definitely got the "weird" factor so far, and I'm interested to uncover more of the main story and what's going on. So far, I've only finished one "playthrough".

Anyone else here played this before?

And, does anyone have any recommendations for similar games, or other games that might fill that "immersive, experiential, unique" niche? I'm sure there's a better definition or genre name for what I'm looking for. Some random games I've enjoyed that sort of fall into this category in my head are things like Firewatch, Before Your Eyes, and Outer Wilds. Almost like, games that pull you into the world, and make it feel like you're really there in some way?
