Not bad
I liked the remix. I can understand not including a video since that would probably just be distracting, but even just a picture of Cats to fit the theme would've made this better. I can also understand the lack of difficulty since this seems to be made for beginners (since you include an apparently mandatory tutorial at the beginning), but at the same time I wish this was harder and that the beats fit the music better. The sound is generally good, but the cheering and announcer shouting "EXCELLENT EMOTION!" get annoying very quickly, and make it very difficult to enjoy the music. You did a good job, but others have done better in the four years since this came out.
