About this game
The developer's description, from the game's Steam store page.
Superliminal is a first-person puzzle game based on forced perspective and optical illusions. Puzzles in this game give you a sense of the unexpected. Players need to change their perspective and think outside the box to wake up from the dream.
WAKE UP
As you fall asleep with the TV on at 3AM, you remember catching a glimpse of the commercial for Dr. Pierce’s Somnasculpt dream therapy program. By the time you open your eyes, you’re already dreaming - beginning the first stages of this experimental program.
PERCEPTION IS REALITY
Explore a dream world where everything is exactly as it seems. Tread carefully as the world slowly unravels around you and subverts your expectations. What you see isn’t always precisely what you get.
MAN VS MACHINE
In this fully-voiced adventure, Dr Glenn Pierce is doing his questionable best to guide you home and out of the dreamscape. His artificial intelligence assistant, however, is having trouble understanding exactly how you’re here at all, and has other plans for you.
