Rate of 5 seen via japanese raw Story this is song based and i have no lyrics i can grab that i can understand so can't comment much. I will say from i could but together the art was able to match the plot in some regard. Art not professionally made. Mostly in black and white. I loved the side by side animation idea. Smooth animation. Not all the side by side animations blended together in the way you thought but they did blend. Character- this was more musical than actual anime so character background and such were not required.
