One finger

Drag left or right. Dodge the red.

The tunnel turns under your finger and the ball rolls on. Red blocks come at you faster and faster. There is always a way through: the tunnel never builds a wall you cannot reach in time.

Boosts

Shield. Slow time. Clear.

Roll over a boost and it works at once. No buttons to press.

  • Shield The ball turns gold and takes one hit for you.
  • Slow time Three seconds at half speed. The ball turns cyan.
  • Clear A flash wipes the blocks ahead. Rare, and worth it.

Every 1000 m

A red banner. New colours.

There are no levels, only metres. Every thousand of them a big red neon banner flashes, the phone gives a tap, and the tunnel changes its colours.

After 2000 m

The blocks start to move.

Spinning bars and swinging blocks join in. They lock in place just before they reach you, so you can read them and pick your gap.
