Your ball rolls down an endless slope through a city of neon towers. Steer to stay on the rooftops and avoid anything red. Every obstacle you get through is a point. Each one is its own building with a drop before it, ramps launch you across the bigger gaps, and each speed tunnel makes you a lot faster. On tilted roofs, stay on the high side.

A D / ← →	Steer
SPACE / W / ↑	Jump (Plus mode)
SHIFT / S / ↓	Dash — a quick burst that lets you phase through red for a moment. Hold a direction to side-step. Works in the air too.
ESC / P	Pause
R	Quick restart
M	Mute

Plus mode adds gaps you must jump, hurdles, dash-gates you can only pass by phasing, and blue shields that save you from one hit.

Classic mode is the original: steering only, every section can be survived without jumping.

Secrets: watch for a gold strip on the right of an obstacle's first rooftop. Steer onto it and a gold road takes you round the obstacle, with coins all the way, then drops you back onto the track (follow the coins). The green roof over a red tunnel and the outside of a speed tunnel are rideable too. In Plus the secret spots hold power-ups: shield, coin magnet, 2x points and slow-mo.

Phones & tablets: hold the left or right half of the screen to steer. Swipe up to jump, swipe down to dash (or use the buttons). Gamepads work too.
