Ninja Climb is a one-button vertical climber: your ninja scales towering buildings, and a click sends them leaping to the next structure. Obstacles arrive between them.
It's endless, so the goal is height, and the timing window narrows the further you get — which is exactly what the format needs to stay interesting.
One button. Clicking leaps the ninja between buildings, and the whole skill is choosing when.
No — it's endless, scored on how high you climb before an obstacle catches you.
Yes — tap to jump. Nothing to install.
