Swipe left or right to change lane. On a keyboard, use the arrow keys or A and D. Green numbers you can ram straight through. Red numbers you cannot — take the lane they left open. Collect the +1 meat, stay out of the -1 spikes, and survive as long as you can. The clock is your score. Pause with the button in the corner, or Escape / P.
Pick a lane, grow your number, and ram straight through whatever blocks the road. Come up short and the run ends. One endless track, no levels.
