when saving pacnoid levels, you must save the file name with the number
at the end designating what level it is.
for a full set of levels, you must save ...1 to ...9
eg. savefile1
    savefile2
etc. 

this is explained in the pacnoid game help information.
unfortunately, you can really only test your first level, the rest you
will have to access via playing the game. i really didnt want to spend
too much time on this sub-game, so minor features like this have not
been addressed.

hope you enjoy.
