Is there a fast way to get to the bottom of the Death Star?

Solution 1:

Sadly, no. I wish there were. At least one does not exist on the iOS version.

Solution 2:

As a workaround, I just keep my Mos Espa Cafe on the 2nd floor vacant. It just doesn't make enough money to be worth staffing. So I have a permanent "!" button which takes me to the lowest non-stocked floor - which will always be Level 2.

Solution 3:

Yes. Hold down one finger while tapping another in the direction you want to travel. The screen will move the distance between your fingers, as fast as you can tap. Alternatively, you can tap and hold one finger, tap and hold another finger, release the first, then release the second finger. If done rapidly, the game will scroll the full distance in the direction from first to second tap - all the way up or all the way down.
