Dahts: The 1-Dimensional Platformer

Dahts Linelander is a hero tasked with navigating across his first-dimensional world and defeating the bloodthirsty Trigon. Your job as a three-dimensional being is to guide Dahts along the various segment-regions. For your convenience, this will be represented as upshift and downshift wormholes on the y axis; aboveshift and belowshift wormholes will be on the z axis. The only tools you need are your left and right arrows, and your space bar.
