A downloadable game for macOS
Phosphene: a phenomenon characterized by the experience of seeing light without light actually entering the eye.
Use mouse to look around. If you look at a "junction," you will move towards it until you look at another junction. The junction must be in the center of your screen in order to move towards it.
The game's duration is based on the amount you look around, so to progress through the different stages as quickly as possible, try not to move the mouse too much; if you want a longer game, look around a lot.
The game ends when you fall asleep.
