A slow climb through the bamboo grove. Switch stalks to eat
the shoots — and don't be on a stalk when a gap reaches you.
Watch for the python climbing up from below, faster than you:
if it catches you, you're done. And after 90 seconds, dead
bamboo appears — you can't jump to a withered grey stretch.
Tap the left or right half of the screen (or swipe, or
use the arrow keys) to move to the next stalk. Three
lives — a fall costs one. A python climbs up about every 30
seconds — keep moving so it can't catch you.
