Shady
There's so much to be said about this.
First off, the loader does not work. Now I'm not really familiar with it myself, but double checking for things like that is always best, I mean, you wan't people to watch this either way, right? The music you choice was slapped on terribly. I assume you thought that increasing the volume on these SFX would make it more intense when it reality all it does is cause some terrible popping through my speakers, you should of known this when you test played the video and right before uploading it. Then there's this issue of dialog you created which seems to be the typical writing for a fan fiction. You break the forth wall over and over again and it's done poorly. You have don't explain anything well enough to follow along with besides "Shady characters have been attacking Mobius". This isn't an animation more so it is just some lazily made motion comic that tries to be Super Mario Bros. Z like everyone else.
It's another generic story of Shadow with how much of a mysterious and lonesome character he. This idea behind him and certain areas of the 'community' that pulling a gun and sword out from under his ass just makes him the coolest and the 'gratest' is terrible.
(That was more of a rant then a review in the last semi paragraph, but everything above still remains)
