Quite posssibly the greatest mario game to date.

Before I review, I'm just going to state that I am a die hard Yoshi-fanatic, but I'll try and make this as unbiased as possible....
THIS IS THE BEST MARIO GAME EVER!!!!!!!!!
Challenging and fun, this game is great for anyone from beginner players to the most hardcore gamers.
Yoshi stumbles upon baby mario and has to take the whiny bastard on an adventure while avoiding spikes, bottomless pits, lava, and all the other deadly weapons. Enough said. What more awesomeness could you want?
The game has a unique feel to it, and an interesting way to determine health. Yoshi can't die unless he touches spikes, thorns, lava, or falls in a bottomless pit. However, he can get hurt by any enemy, and when he does he has to reacquire mario before Kamek's toadies beat Yoshi to him. Oh, and did I forget to mention the gargantuan, all-consuming bosses that Yoshi has to battle? nough said.
This game is fun from start to finish, and puts all other 2-D platformers to shame!
No, not one part of this review is biased.
10/10
By the way, If you are so good as to get 100 points on every level, something neat happens... If you've done so, You'll know what I mean when I say: "Can you beat 256?"
