Yoshi Touch & Go is a Nintendo DS game in which the player must guide Yoshi, who is carrying Baby Mario on his back, through a side-scrolling course. The game is almost entirely touch driven, using the DS's stylus to fire eggs at enemies, trap them in bubbles, and build bridges or ramps for Yoshi to walk on.
Use the two screens to complete the game - for example, you can draw clouds together to block Mario's enemies
