Game Maker Tutorial: Top Down Shooter

A tutorial about how to make a simple top down shooter in game maker. I made this mainly because of a request from HZSOLTI9, though there were others who wanted a tutorial as well. Unfortunately, I couldn't show how I did a lot of the stuff in some of my top down shooters, but hopefully this helps some people anyway. I coul possibly make more tutorials on this, for things like different enemies and weapons. I think I might have gone a bit too fast with this tutorial, and I don't think I explained things as well as I did in my other one. Though, that is somewhat understandable considering this is a bit more complex. Tell me what you think... I would like to have some feedback on this tutorial. Was it too simple or too complex? Did it explain enough or did it explain too much? Should I do tutorials in drag and drop or GML? I want to know what people think, so I can hopefully improve if I make another one in the future.
