I understand constructive criticism but...
here's the thing about a Mario vs Sonic fight:
They're both platform gaming characaters, not fighting characters, therefor everybody is going to have their own preference for the style they should fight in. Every fight I've seen features a style from somewhere else. Here, it was DBZ, which is cool. Anothert one I've seen had a style much like Street Fighter. It even had a hadouken. Just like preferences on who should win, everybody has a prefernece on the fighting style as well.
So, anyways, I loved it. I love seeing all the ideas come to life for this fight. The 8 instead of ten was because the shortness of it as well as the way the two characters seemed to be cut and pasted onto the background.
On the plus side, the growing intensity kept me entertained as well as the implemented Super Sonic and star/cape Mario. Cool bit right there.
