Really simple game that been resting on my HD for quite a while.. ;)
Simple to make, not so simple to solve though. Click on the windows to turn the light on and off. Press the 'R'-key to reset a level.

Story/Objective
Simply turn off all the lights, blacking out the house so that enemy bombers can't get a target.

However, it seems that in this old house, the electrician quit when he was only half-way done wiring the place, and that the eccentric previous owner wired the house in such a haphazard fashion that switching just one light on or off has an effect on the lights in adjacent rooms.

What a nightmare! Your goal is to blackout the house in as few moves as possible.
