Guide the urthwurm through 10 levels. Press the SPACEBAR to make the wurm rise
and release it to make the wurm dive. There are 3 difficulty settings; easy,
normal and hard. At the end is a special bonus, different for each difficulty
setting. You can pause the game by pressing ESC or P. Press any key to unpause
and continue.
Urthwurm is a quick remake of a popular Windows3X/PalmOS game called
SFCave
which was made by SunFlat. This game was made by BdR using Turbo Pascal 7.0.
