Change your name...
	Skip Floors...
	Various Steam Achievements...

Enter the controller settings and select "player one" instead of "Player 1" controller. You can then type any name you wish.

Before you start a run, head to the Options menu and click on the dwarf located near the screen's lower right side. A "Secret Dwarf" prompt will appear, and you can replace that text with Skip #, where '#' is anything from 0 to 36 and represents the floor to which you wish to skip. Note that you can only do this before you begin a run. You'll head directly from the tavern to the desired level, and return to the tavern when you're done.

Complete the indicated task to unlock the achievement.
