In Tiny Death Star, you can get to the top of your tower by tapping on the top of the screen while avoiding the "Add Level" button. However, the only way I can find to go to the bottom of the tower is to wait for someone to want an elevator ride, and tap on the button to give them that ride. Is there any other hot-spot for getting to the bottom of your Death Star?
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.
