It was good and bad at the same time
Like the previous reviewer said...
"Just pictures flying around a screen" isn't that good.
You really could make it become better if there were proper animations while they were "flying around a screen".
Then the fight-scenes would be excellent! All those Luigi-clones throwing themselves upon Mario... that's actually good! ...but the way you did it it also looked goofy at the same time.
Also I missed some classic Mario-soundeffects...
...and that background-JPGs looked horrible.
