How to play
Light beams travel in straight lines. Tap a mirror to turn it, tap a prism to flip it. Prisms split light into red, green and blue. Each target needs one exact color: beams reaching the same target add up, so yellow is red plus green, and white is all three. Filters only let their own colors through. Light up every target to win.
