Uhh...
Mario's sprites were jagged in my opinion, the "Fight" scene was basiclly the best part, good use of sprite SFX at that part. But the text came and gone too fast, be glad I can read semi-fast. Well, I can see that this IS your first submission, so I ain't gonna scold you, heck, i'm not sure if my first submission will be any better. I give it a 6, just for it being your first.
