This is the lesser-known companion Playstation game to the classic anime Serial Experiments Lain. There's a downloadable version as well. The bottom of this page has the chart of keyboard controls.
Also, the gameplay is highly unconventional. It's not like a regular visual novel. It has a totally different style and purpose and interface than Disco Elysium, but it takes the same sort of patience and open mindedness.
Oh cool definitely gonna check this out, thanks :))
