- Added an atexit(3) cleanup handler for endwin(3).
- Added hiscore/level tracking and display, now requires 33 lines.
- More keys are accepted for movement.
+- Highscore saved/loaded to/from file.
BUGFIXES:
- There are some globals in pacman.h that should really be macro
definitions, and/or moved to the main module.
- Uses ad-hoc command line arguments processing rather than getopt(3).
-- Should save/load/remember the high score.
- Should support monochrome displays.
- With the colors used some ghosts can be difficult to see properly under
common terminals+screens.
