Hello! Thank you so much for playing, and sorry you've been having difficulties! For the first with the screen freezing, does it freeze at certain times, or does it seem random? You can try turning off animations in the preferences menu and seeing if that helps.
For the second issue with the names, are you saying your entries are not appearing in the text box? Or are they changing after you try to type them in?
For the third with the hair, that hair is just under the "Hair Back" section, meaning it isn't meant to be seen as a hair style all by itself. It looks better when combined with a "Hair Front" option higher on that list.
Again, we appreciate you playing, and hopefully we can help you sort out any technical difficulties!
