Shoot rainbows in the sky! Don't let the rainbows hit the floor. At level 3 golden rainbows will appear which take multiple hits. At level 5 X's will appear which your shooter cannot touch. There are 20 levels and a final boss level.
@curgyrn for the idea and initial game (Rainbows didn't move, and were the only thing you could shoot, no way to lose or win)
