The demo featured two levels that allowed us to explore Link's native island just before Tetra makes her appearance for the first time and battle the Helmaroc King.
In the "Island Stroll Outset" level, we were able to test out the game's new Miiverse-incorporated bottle system. Once a bottle is plucked off the ground, the message can be read below on the Wii U's GamePad. A representative told us that bottles would typically be strewn about beaches for players to pick up.
We also had the chance to test out the game's new, faster sail, which can be equipped with one touch of a button and makes ocean travel substantially quicker.
During the Helmaroc King level, we were able to use the GamePad to aim with Link's bow and arrow. Additionally, players will now be able to move when in a first person perspective. New items or weapons can also be easily equipped or traded by touching and dragging them on the GamePad.
The Wind Waker's HD upgrade makes its visuals appear noticeably brighter and smoother. Environments no longer appear slightly block or sharp in the corners.
Nintendo announced earlier this week that The Wind Waker would launch for Wii U in October.
