Story
The full story is only told at the end of the game.

Level 1
Run right until you find a wall. Join the nodes, run past the fault line, and join the new pair of nodes next to you. Jump up and unjoin the node. Run right to find a teleporter!

Level 2
Up the ramp you go! At the top, join the nodes and jump down. Unjoin the nodes to find yourself on a new ramp! Climb this one, too. Join the nodes, jump down, unjoin the nodes (this looks familiar), run up top, and look! You're in a new section! In here, Join the node on the left with the top node and jump on the ledge. Unjoin the nodes to get Zapo caught in a trapezoid. But you can free him by joining the node on the right with the top one and jump down to the teleporter!
