SMB3 Final Boss DX

What if a NES game was pumped up to today's standards with action? This game takes it up on the offer.
Bringing in new elements and a great visual impact on this classic scene from SMB3's final boss battle, you're sure to be amazed (at least I hope so).
This one was for a minigame competition, so bear with its shortness!
Many of you probably know how fond I am of the effects I make. I like to think of them as final touch.
This time, I wanted to take an already-made game and just see how much I could add to it!
