This game has you enter a place you shouldn't, a portal, an actual liminal space between the real world and the world of dreams.
The main gameplay loop is looking at a subway map, picking a station to go to, and exploring, with items you pick up at one station coming in use at another.
Each station is a pure fantasy, mostly disconnected from the others. It's reminiscent of Miyazaki films like Spirited Away or My Neighbor Totoro (with their subway/catbus). The locations aren't intentionally scary, although some are pretty trippy.
I forgot which station I entered in and it was literally the last one I went back to. I ended up seeing everything, and it was a lot of fun!
To describe the vibes, one early station has a market run by people made of wood; another is a station almost identical to our world, but subtly not.
There were some spelling errors, mostly in the first few pages (like 'rennovating'). There was a pretty bad bug where trying to click on 'alight upon water' to transfer from the brown line to purple line going north gave a twine code error. You can get around it by going south instead and turning around. I think that one other station was like that as well.
Overall, a pleasant game with a few bugs.
