2d Shooter Tutorial (alexfortsch)

This is my tutorial complete of my 2d shooter. This is just the basic tutorial, excepted i duplicated the level one more time so that I could have a level 3. Proposed modifications: 1. Custom Music Change 2. New Levels with more enemies 2.5 Change levels 2 and 3 to be more unique 3. Try to add a unit spawner, with a "free for all" / "sandbox" mode
