A vast jungle stretches before you. Drag your finger to steer your serpent
through the undergrowth. Red-marked creatures are your prey — devour them
to grow long and thick. Slither up trees to hide in the canopy, and push into
the city at the jungle's edge to hunt among its streets.
Beware lions, buffalo, crocodiles and elephants — while you're small they
will kill you on sight. Grow large enough and the hunter becomes the hunted:
you can swallow them whole. Don't bite your own tail, and don't slither off
the map's edge.
