Amulet Causeway

Collect both amulets, then reach the gate. Conjure bridges beside your current position; recall empty bridges to reuse two charges. Walking into water is dangerous. In build mode tap an anchor, then conjure or recall. In walk mode tap an adjacent tile. Undo restores bridges, charges, amulets and explorer position, even after a fall. Aiming, modes and rejected actions are free. No timer.
