Part 6: More...
Here goes what you will do!
(And maybe what I will do if I find a way to edit this tutorial to add more complicated stuff later.)
Also, if you have any suggestion, feel free to tell me in the comments, so I will add them to this tutorial.
You can download the final file, so you can play around with what I've done, or add more, so you'll be able to make other tutorials, or your own game.
Anyway, have fun!
