Colorful game! Seeing the circle change colors is nice!
I did notice when playing, that I was constantly firing a steady stream of light rays despite not pressing space - I don't think that's intentional? On the other hand, I do feel like just spamming light rays is the best strategy, due to the reflected light rays only subtracting 1 from your score.
Spamming light rays creates a very colorful view, too!
