I love the music choice for that! I could imagine a better fitting melody, but it'd take ages. The references are awesome, although I personally don't know some of those. The sound-action timing is the closest to perfect, and the sound effects used are just right. The concept of environment involvement and 3d stage for 2d characters are very amusing and far-going. Safe A+
P. S. There should probably be some traces of damage on the right wall (1:50 point).
