Super Mario Maker (for Wii U)

This mode uses the Wii U gamepad to its best possible extent, taking advantage of the large touch screen and stylus to give you a canvas to draw blocks and coins, and drag enemies and power-ups.

Besides basic level layout and graphic style, you can set multiple areas connected by pipes and doors to add complexity, combine different objects for unique effects (like a Thwomp in a cloud that seeks you out before dropping, or a Bullet Bill launcher that fires mushrooms), and even place sound effect triggers (and record your own sound effects with the Wii U gamepad's microphone, but recorded sound effects can't be uploaded and shared with your levels).

You have to beat your levels before you can upload them; the game doesn't let you share levels that can't be completed.
