It's pretty self explanatory... Make yourself! (Or someone else, it doesn't really matter). Press the button under hair to switch the hair, and it is going to show you hairstyle in black, orange, yellow, brown, and violet colors, once you press the button at a time. You can't go back right away, you will have to see everything and then it will loop back. Eyes, nose, mouth, and clothing you press and it gives you different options. Same with looping. For skin color, just press whatever circle you like. Glasses, you can press it, and see different options. It will take you back to no glasses version. That's pretty much it. Oh, you can take a screenshot if you want to save it. (You don't have to credit me, but you can if you would like to). Enjoy!
I looked at other Make Yourself scratch projects for inspiration.
