Lame. Another SMBZ flash.
I love reviewing these shitty SMBZ ripoffs and there's no end in sight. This is the second Mario Bros. Z intro I've seen with the DBZ Kai song. Only the other one had better animation. Plus you used the Japanese audio, which is ten times more irritating.
Your sprites are low quality and your animation is twitchy. You also need to learn when to use graphics instead of movie clips and vica versa. I can forgive the shitty animation if you put out an entertaining story, but for an intro/test? Not a chance!
