Thank you very much! To answer your questions-
We are going to try to keep adding more color options are time goes on, there are just a lot of layers to alter since there are so many hair pieces, haha.
You can change your last time now, but once you pick it out you're stuck with it for the rest of the game. The first name can be changed, though. So as a kid you could name yourself "Sam Meadow", for example, and later on change Sam to Chris or whatever else, but you'll still have the last name Meadow. If you tried to change the last name at the start of the game and weren't able to than that's some type of error and we'll get it fixed up!
