I'm a little late here .

I downloaded the demo if that's the right one. I liked the initial music that was playing throughout the menu screen and game, I feel that it could also suit other types of scenes.

And on that game btw, I think you should experiment with more movement allowable and some more speed to it and see how it feels that way, might keep the excitement up a bit more (it's not too easy either which is good lol).
