Keep running. Every 1000 m the scenery changes: the rooftops, a tunnel where you jump over cars and climb onto trucks, and the jungle. The further you get, the faster it goes.
✨ Double jump: already in the air, tap the right half again. That's what you need to climb onto the trucks in the tunnel.
♥ Three lives: when you crash you go back a few meters, start off slower and for a few seconds nothing can touch you. Your speed comes back on its own. The third time, it's over.
You can jump and duck at the same time, one finger on each half. On a computer, space or up arrow to jump (twice for a double jump) and down arrow to duck.
