Certainly decent
It seems like you were really working on making an experimental flash with this. I know it does not say that in the description but that is how I interrupted it. The only problem is that it is in fact fairly short with not that much point. I recognized the sound effect as being from that one bomb game with medals. This was certainly creative, as I had absolutely no idea what was going to show up next on the screen. The green main character kind of reminds me of Oogie Boogie.
It seems like you were vaguely going "Ghostbusters" with what his appearance was. I love how it transitions to a scene where the art is completely different. He did seem to really contrast with the background in the first half of the cartoon. It was nice to also know what he was thinking. It doesn't matter if a story makes any sense, as long as the animation is good.
