This is the greatest thing ever made. Something I always dreamed about as a kid. What if other Nintendo characters were in Mario, or vice-versa. Well, it's 20 years late, but I'll take it. I heard about this game from Kotaku, and I've been playing it all day. It's amazing. Most Flash games I play for a few minutes, and that's it, but this is an alteration of a classic I've been playing for over 20 years, so, who knows, I might play this for that long.
