In Mario Maker
for the Wii U, players use the GamePad touch screen to easily drag and drop elements they want in their levels. They can place blocks, pipes, lifts and enemies anywhere and play through the level. Players can instantly playtest and edit their creations on the fly. If something isn’t working, go back into edit mode immediately by tapping a button and make tweaks until everything is just right. With the tap of an icon, users can even switch the visual style between a classic 8-bit Super Mario Bros. look and the HD world of New Super Mario Bros. U.
