Pretty good for a first game
I started out like you too. I had basic knowledge so obviously, I started with the simplest type of game, a first person shooter. Some things that would've made it better, work more on the graphics, more levels, more sounds, copy and paste the following code into a movie clip Mouse.hide() now make a second frame for that movie clip and have it say gotoandPlay(1) now put that on the main timeline. Mouse.hide() obviously hides the mouse. Something that I made up (I'm not sure if anyone else thought of it too) is this. i get really frustrated when I'm playing a first person shooter and I accidentaly right click or change the quality because there isn't a quality changer and then the mouse isn't hidden anymore. But because the gotoAndPlay(1), it loops the sequence of hiding the mouse. Can't wait to see more from you. Good luck.
