There really isn't any direct music but the sounds are great. I enjoyed the gameplay as is but wished for more. The system used in the game reminded me more of a background puzzle than what it is. However the game is too intense at once. To make gameplay more approrachable it would do good for perhaps maybe an A.I that takes over for the player for a minute. Just for a break in game to do something else within the game. And I don't mean actual A.I I just mean like a character or mechanic or something. Basically something to do besides the main loop.
Otherwise the art was nice and you made a polished and playable game.
