There is a new gameplay video for the game on nintendolife. This one is focusing on the co-op aspect of the game and shows the first 10 minutes of the game. One player controls the movement of the ship with the wiimote and the other is operating the ship computer on the gamepad.

As developers announced on twitter the game is finished and submitted to Nintendo, so it will be released soon.
As you can see from the footage below - which, be warned, contains somewhat unrelated references to Colin Farrell's early televisual career - the game makes excellent use of the Wii U's two-screen system, with (in this case, at least) one player guiding the ship on the main screen while the second - assuming the role of an engineer - is in charge of other duties, such as turning on various systems and controlling the pitch of the ship. Although we didn't try it out, it's possible to add a third player who is in charge of navigation.
