Maze: Path of Light is a puzzle game about navigating darkness. You move through a maze that is only lit around you, so the map has to be built in your head as you go — dead ends are only obvious once you've walked into them.
The pacing is deliberately slow and the atmosphere does most of the work. It's a thinking game rather than a reflex one, and the satisfaction is in the moment a layout you've been fumbling through suddenly makes sense.
Follow one wall — always keeping your left hand (or always your right) on it. In any maze without loops this eventually reaches the exit, though not by the shortest route.
No — it's a slow-paced puzzle game about navigation rather than speed.
Yes — a light browser game with nothing to install.
