combining all of the options together will generate way too many assets, which is why they are currently split up. I recommend, depending on the game engine you are using, to create a layered character. alternatively if there are any specific combinations of colours you'd like to see, I'll merge these specific files for you as well.
I'm alse updating the text here on the asset pack in order to avoid any future confusion. Thank you for making me aware that it might be an issue :)
