Energy Archipelago

Enter dark islands full of hidden electrical parts. Batteries are tucked in caves, bulbs on rooftops, and wires in shipwrecks. Find them, haul them to the workbench, and build the circuit that powers the whole island. Wire it wrong and things pop, spark, and smoke. Wire it right and the whole place lights up. Each island teaches you something new about how electricity actually works, and by the final one you're combining everything into a system that would make a real engineer proud.
