Its Yoshi on rails!
First of all, this isn't a game. Its a demo of what this game could've been. It has 4 modes to choose from, but they are all pretty much the same,.
Yoshi is on rails, meaning you can't control his movement. You tap hime to jump, and tap an empty area on the screen to throw an egg. You can draw little clouds to guide the little green dinosaur. The game play is probely the highlight of the game. I enjoyed drawing clouds around enimies to put them out of their misery.
This game is a huge let down, Nintendo still made me pay full price for this demo. I guess this is one of those games you pop in a year or two later to see if you can beat that old record. Thats how I look a this snore fest.
