This is one of those “standard” little demo programs almost everyone makes.
There is nothing particularly interesting about the whole setup.
It uses OpenGL for the graphics, FMod for the sound, and my own archive format for the data.
It is a fairly old project, so it has some speed issues, as well as possible graphics glitches when it tries to setup the window.
Arrow keys move you, space shoots. Unfortunately, I don’t think there is a “exit game” button, and alt-tab may not work as expected. Here’s your WARNING! You’ll have to kill it with taskman, possibly blindly. Like I said, long long time ago, and I don’t have the source anymore to be able to fix it up.
