Reflections is an instantly addictive, beautifully done flash game. All you have to do is guide beams of light so it reaches lightbulbs, but not bombs. At your arsenal you have mirrors, double mirros, refractors, and splitters. Sounds simple, but it gets difficult quick. Link is Ad-free, as usual.

Hint: Think of where your light is going to END up, and build your path backwards. Good luck!
