I think this game has something. It's a simple concept but very interesting and challenging. The UI design is not the best, and the parallax background doesn't look great(I think some resolution issue causes it to not take up the full screen...) But the color scheme is nice. The audio isn't amazing either but the gameplay really makes up for it I think. Nice job.
As a side note if you're into really challenging games you should try mine. I don't think anybody has beaten it...
