If you click on 'Set Gender' in the End of the World shrine, before clicking continue on the tutorial, the game breaks and you can do nothing.

There's also more, as well. At some point, not sure when exactly, exploring Welci & St. Zure took me to the clothed changing page, and selecting 'save outfit' just brought me back to the clothes changing page, so I was stuck there. 

Also, if you go to cast the Zodiac Naming spell, and then back out without actually doing it, the game will get stuck on a blank screen.
