Does it have a base character that I can customize?
Hello and thank you for your question. The character is as seen in the images. There are no clothing layers but you can modify the sprites as you wish. Hope this helps.
Look into pallet swapping as a start. Not sure if you're a programmer or what engine you are using but you be able to change skin color, clothing color and stuff just using one texture file. Let me know what engine you are using and I may be able to help. I have a pallet swapping system working in Unity.
