Hello! You will not be able to add the Character Creator itself to your project. This tool let's you design sprites in a character creator setting and export the sprite sheets to add to your projects. So it's perfect for NPCs and characters who have a single look. We do include all of the individual sprite sheets in a zip file with your download, so you can recreate a creator in your project for customization in game. You are free to use any sprites created in this program and any of the individual sprites for a creator in your personal or commercial projects (just not another sprite sheet tool lol)! Credits to Memao are appreciated!
