i like the creativity within the environments a lot, especially the maze full of paintings. And the ability to call Center to get more information about the world was a very cool mechanic.

(also i wish itch had better tools for marking spoilers)
Also the wrongside being sort of a character itself was neat ending twist. it was a lot more interesting then the general scp style spooky goobers that backrooms media usually go for.
