Hello.  I'm going to make this as brief as possible as this is in my opinion the worst Mario hack ever.
Overall: 3
I rated the overall of this game a 3 because;
-There were no new sprites that I could see.
-There was no new sound
-The Map was exactly the same as far as I could see
-no new text
I only had to play the first level to see how bad this game is.  I could rant and rave forever about it, but I'll just continue.
Graphics & Sound : 8
No new sprites, no new sound, but I couldn't see it in my heart to rip on SMW's sprites and sound.  I've just always liked the SMW sprites and sound.  But I would've liked to see something new.
Addictiveness: 1
A 1 for addictiveness? What?!  Allow me to explain myself.  The first (and only) level I played was just a big flat plane with enemies that only require one jump to defeat. Then you reach a chasm.  But it's a Mario game, so you can just jump across, right?  Nope!  The chasm was two blocks too wide for Mario to jump across.  There's where I stopped playing.
Story: No story as far as I could see.
Depth: 1
You literally can't get past the first level, not because the game is hard, but because you aren't supposed to get past the first level.
Difficulty: 1
The only playable level was surprisingly easy for a game called "Super Mario Nightmare Edition".  I suppose that the hack maker decided that since the level was so easy he/she would just make it impossible.

Not bad! Next time be a little more specific and split the categories into paragraphs instead of the whole review being one giant paragraph. Separating the paragraphs makes the review easier to read.

TheSpelunkyGuy : No Mario game is terrible...except Hotel Mario and Dr. Mario

But this isn't the best first review I've read, but this is a good review. Next time: I'd like to read more content to this, and also try categorizing into paragraphs like PacmanandMariofan:said.
