This is a simple asteroids game written in C using the curses library to render. It samples bitmaps at different resolutions to render, so looks best in a huge terminal with tiny text.
$ make
$ ./as
To control the ship, use the arrow keys (left, right turns and back/forward accelerates and decelerates). To fire, press space. To zoom in/out use + and -. The p key pauses, and F1 quits. Or just hit control-C.
