Sloppy
Honestly, I didnt find myself laughing, more like a 'wtf' laugh (not in a good way). Almost every joke (and there's 4 of them) consist of mario getting hit by something, or some kind of low budget explosion. Not to mention, the sprites were out of scale, and some tweens were overly slowed down, which doesnt leave a good impression of effort. The whole thing was just sloppy.
And learn to compress sound, please...
