No gameplay, 0/5(submission rating), 0/5(Review rating). My advice is to re-upload it into the movie section, if you want people to see the Mario thing, removing the bit where the gameplay starts. If your serious about your game "Grim Ronin", uploading it into a separate movie upload as a trailer.
After I watched the animation though, I think you could make a good movie off of that instead of a game. I actually don't know of any games including Mario sprites. You should try that, submitting a sprite movie, You appear to have plot, and humor along with good animation, I think you can make something great. I can't say anything else because there is no gameplay so I can't say if it's good or not. As far as the extra trailer, I don't think I'd be particularly interested in trying it.
