Two rails, one button, no jump, tap to switch lanes and thread the obstacles for as long as you can.

How to play
A pure one-button endless runner. Your runner races forward on two parallel rails and you have exactly one move: swap between them. There's no jump and no brake, read the oncoming obstacles, pick the safe rail, and keep threading the gauntlet as it speeds up.
The runner moves automatically; you only choose which of the two rails it rides.
Tap to swap rails and slip past blocks on the opposite lane.
Some hazards block both rails with a gap to time, switch at the right moment.
One hit ends the run; your distance is your score and the pace keeps climbing.
Controls
Desktop: tap/click anywhere or press Space, Enter or Up/Down to swap rails.
Phone & tablet: tap anywhere on screen to swap, that single tap is the whole game.
Tips & strategy
Look ahead, not at the runner, decisions get easier the further up the track you read.
Avoid panic double-taps; an extra swap can drop you onto the very rail you were dodging.
On dual-rail hazards, commit to the gap early so speed doesn't catch you mid-swap.
