Dont be so hard on yourself!
I actually quite liked this movie, especially when he was flying towards bowsers castle all dragon ball z style, and he was tearin shit up and kickin ass on the way. That was like evil pissed off Super Mario. Good flash, could have been a little longer, and a cool fight scene at the end against koopa would have been cool, but this is only ideas to improve, this is already a good flash ^^. The ending kind of threw it off though with him dancing...
