I think the music you use adds a lot to the tone of this story, because without it, the story would have been at a paradox with the colors of the backgrounds. While the tone isn't definitely my cup of tea, you definitely have an interesting way of making everything work, so definitely props to you for that.
Another thing that's definitely working in your favor is that because I haven't looked at your other works, I still get a sense of what's going on, which only the best of story can manage to do flawlessly without throwing off the person too badly, so that's definitely a plus.
The only real con I had was the arrow button in the center of the screen, since when I first looked at the screen, the arrows at the side of the screen blended in a bit too much, so you might want to have the arrows on the sides stick out a little bit more so people aren't guessing as to how to get the story to move forward (hence then 9 instead of 10...), but other then that, there's nothing else wrong with the story.
I hope this review has been help.
