Freaking sweet!
I could not help but think that you were influenced by some scientific theory about color. Whatever the inspiration, this was fantastic because it was very simple to understand. Even as it got harder, I was still not frustrated by how hard it was! I love all of the designs put into this, like the space ships which are there for really no reason. I was at first fearing it might be too short, but luckily it got longer. You definitley know how to have the right number of levels as it is one of the most satisfying puzzle games I have ever played.
