Hi Time Traveller,
Easy to get working in unity
1. Download unity
2. Install Unity
3. Download CC2D.unitypackage from your library
4. Double click the package and unity will open it.
5. In Unity go to Window>Character Creator 2D>Create character
If you close the window by accident etc, just right click the play button in the top middle and it will close the run state of it and you can start it through the window menu again.
Hope this helps,
Kombowz
