Stop moving and you go out.

Not a metaphor and not a difficulty setting. There is no health bar, no lives, and no safe corner to think in. There is a small bright thing in the dark that happens to be you, and it stays lit for exactly as long as it keeps travelling.

Tap where you want to be and you dash there. Cyan light is fuel — fly through it, and the longer your chain runs the further each dash carries you. Everything else out there wants that light, and the only way to break any of it is to arrive fast. Arrive slow and you are the one who breaks.

That is the entire game. The rest is the part where you get greedy.
