I guess you have an idea, already. This is how I started, on July, 4th

I did the lite-C tutorial, rich advised. It`s fantastic for beginer. Instead of working with toturial files, I started my first project directly - First things for example were creating an own level or only showing Scores on the screen. At the end of the tutorial, I´ve got this:

My First 10 Seconds with Gamestudio

And it`s nothing more, than you can see. A Player-Entity, which can move and shoot and some Enemy-Entities, which (c_)move into the level.

If you know a little bit about a C-similar language, you will get cool results within a few weeks. If not you have to learn some more about lite-C before.

Cheers
