Nice!I didnt know you did sprites!Well this one really put a smile on my face :P Now here comes the in-depth reveiw ;)
Graphics: 10-You can't really go wrong in graphics with sprites can you?
Sound: 9-The sound was good but as you said,Mario's voice was pretty fast.
Violence: 8-If you cant figure out why i gave you and 8 for violence you must be pretty dim xD (jk)
Interactivity: 6-There were buttons...but the whole scene selection button thing pulled this down
Humor: 9-This was damn funny!:p
And that concludes my reveiw ;) Good luck!
