Mr. Light, the electrician, must navigate through a series of buildings to restore power after a massive earthquake strikes the United States of America. The game is divided into two parts: exploring the building's electrical circuit to find breaks in the wire and fix them, while avoiding pests and hazards along the way.
Gameplay involves climbing ladders, jumping between floors, and unspooling wire to make connections. Capturing a thief will reward the player with valuable items, including a bell that grants an extra life. However, players must be cautious of insects, animals, and electric sparks that can harm or kill them.
The second part of the game takes place in an underground sewer area where Mr. Light must use his flashlight and agility to navigate through the dark tunnels and find an entrance to the next building. With limited resources and a high risk of danger, players must be strategic in their approach to succeed.
