Fos

Fos is an endless runner set in a dark world. You use a light to reveal platforms and draw lines to mark their locations, then navigate procedurally generated levels. Battery power for your light and memory for drawing lines are limited, so you must manage both as you try to keep going without falling.

Robots and levels

You unlock three playable robots as you play. Each has its own procedurally generated levels and abilities:

• Reggie: a regular robot with a light switch.
• LineRider: can walk on the lines he draws.
• Anti-Grav: goes up when he falls and down when he jumps.

Game modes

• Normal mode: see how far you can get before running out of resources or falling.
• Time Attack: travel as far as you can in 60 seconds.

The game has seven achievements to unlock. Progress far enough and you may uncover the secret of the dark world.
