Rover Footbridge

Guide @ to the gold-edged exit column. Mission 1 crosses the gaps; missions 2 and 3 also require every ★ survey beacon at its exact height. The rover walks only right, can climb one cell, and can safely drop at most one cell. Read the next-step forecast before walking; it checks only the immediate step, not the whole route.

Select Bridge or Stair, then a map anchor and Place. Bridges are two horizontal cells. Stairs are two across with one above the right cell. Pieces must touch or overlap existing terrain or construction, add at least one new cell, and never overlap the rover. Floating builds are rejected. A beacon needs empty air for the rover to occupy; do not build a block over it.

Each mission has separate limited bridge/stair stock. Undo the latest build before the first walking step. Retry resets only this mission; success unlocks Next mission. Arrow keys focus map cells, Enter selects; all tools have labeled buttons.
