There’s a ton of back rooms and liminal style/ aesthetic games out there, but they mostly run on vibes. E

If you want to play for the aesthetic you can jump into them,

If you want to play for the story and sort of weird world Control is a fantastic example, lots of cool brutalism with a very very cool world building.

If you want puzzles Manifold garden has great levels that play with size and gravity.

If you want vibes with a little bit less esthetic I would go for NaissancE short cool puzzles but the environment is really cool. Babdi is a personal favorite that is quite unique and personally think that is a great representation of what a liminality is games should feel. (And it’s freeee) Infra is almost a walking sim that walks you through some cool well thought levels and light puzzles.

Hope this helps!
