Land. Walk. Link.

Follow a marker, hike or fly, then hold E to link a relay. Walking, swimming and VTOL flight on procedural cube-sphere terrain.

The surface is the puzzle

Kepler-442 b is temperate and oceanic. Deep water swims. Slopes shed you. Jetpack fuel regenerates, but ridges between beacons cost time if you burn carelessly.
