This is a well made game with an original idea. You're a robot who needs to reach the roof of a building to fly away in a spaceship located there. You need to open numerous doors in numerous rooms to get there. The doors are mechanical and are opened through cog chains. Your goal is to fix these cog chains in every room to open the door. There are cogs with rotating lights. These cogs are driven by motors. Normal cogs can be removed and if there's a yellow cog it's an empty space where you can add a new cog. Your goal is to conduct the rotation of a motor driven cog to the door and to make sure the last cog will move the door upwards. You have 5 minutes to reach the roof.
