A minimalist game with very few controls, you are able to rotate the torch of the universe and send out pulses of movement to try reposition your prisms and redirect light onto the planets but doing so causes the torch to flicker and may cause planets to die.
Starting off with a awe inspiring, eye pleasing colour to watch and then the lights go out, one by one, darkness starting to encrouch slowly will you keep as many alive for as long as possible or focus on one planet and try to develop it as far as you can.
