I don't know the full story behind the level. To me it seems like the fact that it is only partially decorated is supposed to make it unique, but it really seems like the level simply wasn't finished. In some parts it is empty, and specifically the default slope blocks actually look ugly. There is minimal air or background decoration, leaving large empty spots. It's a shame because the deco that actually is there, is good. The colours are vibrant, and it could have been a cool neon level. The effects and flashes that are there do a phenomenal job at syncing with the music. All in all this level is wasted potential, but I admire the good things that are there.
