Very "been there done that"
The animation itself was fairly solid, but really was almost the exact same thing as the first Mario Pown. However, the part with the coins looked really good in this, which I'll give you props for.
The audio, while somewhat fitting, is increasingly obnoxious. When it's getting near the end it just goes batshit and goes from mildly irritating to ear-bleeding.
While the flash is an improvement over your first edition of it, it really has nothing terribly special about it. Sprite animations like these are overdone and stale - not to the point of pointless Naruto and Dragonball Z sprite fights, but still a pretty tired convention. I hope you can move on from such overdone genres in the future and branch into something of your own. While this is okay, if you want to get anywhere you're going to need to strike out on your own.
