Well its the first of its kind, but not very good.
Want a summery of how this flash works?
Mario walks along the screen like in a normal way like you're playing a game.
Mario finds a hidden vine and climbs it.
Mario goes left again, sees the flagpole is surrounded by baddies.
Mario grabs a megamushroom, and kills them all by farting.
The end.
Not laughing? I don't blame you, I don't care if this was a quickey, it's just too underdeveloped and only has the one joke, fart jokes CAN be funny but the simple idea of getting big and farting is barely original or humorous in any way.
To be honest, the graphics aren't too well handles either, he could've at LEAST allowed smoothing on the Mario sprites, they consistantly look jagged and pixelated, a no no for polygons.
And as far as accuracy goes, not too accurate, the ammount of blocks is obscene, you don't ever get THAT many blocks outside, secret exits have RED flag poles, and you cannot get 5000 points from flag poles, all minor details though that don't really matter, but would've been nice considering the humor was lacking.
If you want something substantial, go elsewhere, this movie consists of one fart joke and poorly handled graphics, it feels like you're watching a rom hack.
