I think the gameplay is interesting however like the commentor before me the camera moves to the corner of the screen and it makes navigating the game impossible. I rated it one star for music as there was no actual music. I thought use of a high pitch tune to represent the intensity of the light was interesting, but it shouldn't be the only sound(aside from the end of level sound). The art is okay but very minimalistic. I don't really see how it fits the theme. It's a matter of opinion but first you have to establish rules before saying they being broken.
Otherwise, the game play is okay within the first couple levels.
