Obstacle Runner Game
One button, one jump, a speed that never stops rising.

About this test
The one-button runner is the most stripped-down game format there is: no steering, no inventory, just one piece of timing repeated forever while the speed climbs. That climb is the whole game — there's no maximum score, only the moment your attention gives out.
What makes it interesting is how clearly it separates reacting from anticipating. The first hundred points are pure reaction: the obstacle arrives, you jump. Past that, the speed outruns your reaction time and you have to jump on a prediction, going by where the obstacle is rather than how close it feels. Players who cross that threshold all describe the same thing: they stop deciding.
Two details that cost runs: jumping while already airborne does nothing, and although obstacles vary in height, a single jump always clears them. If you hit one, it was the timing, never the height.
How it works
The score rises roughly ten points per second survived while the scroll speed increases continuously. The 0-100 scale runs from 10 to 300 raw points.
