To  continue past a point that tells you that a certain number of
tokens  or  babies  are  required,  edit the LEVELS.TXT file, find the
section  describing  the level you are on, find the line "req tokens="
or  "req  babies=",  change it to a number lower than what you already
have,  and  restart  the  game.  You  can now enter where you couldn't
before.
