IMPROVEMENTS
- Allow to build against BSD or other X/Open standard curses(3)
-
- Use getopt(3) and atoi(3) instead of ad-hoc argument management
-
- Make UFO missiles two animated rows to be closer to those in the
original game.
-
- Add a curses(3) atexit(3) cleanup handler.
-
- Use stdlib EXIT_SUCCESS/EXIT_FAILURE.
-
- Add high score keeping and display the scores on the title screen.
-
+- Load/save the high score from/to file.
- Bandwidth efficiency improvent and addition of the -f option to
lower the frame rate from the default (very high) 50, if necessary.
