Good, but... weird
This is a solid animation set to Hyadain's classic song, but... why did you take a Mario song and have it sung by different characters? I mean, they're even calling each other Mario and Peach just like in the original, but they're not those characters...
Only problem with the animation is that it goes way out of sync about by the Luigi verse. Not sure why there are two versions in the same animation, I say just stick with the flash version itself to keep the filesize down. The video version was out of sync since the very start. I DOUBT it's because of my computer, because it runs really well and I haven't seen this problem on more elaborate animations and games.
