Bugfix provided by Einar Saukas and Bandit:
  • The game cannot be completed because of a bug which prevents the gun being discovered in the circus. The problem is that it was originally written for a "Quill A" database but converted to a "Quill C" database (presumably so that it could include Illustrator graphics). The gun discovery sequence is controlled by flag 28, which is reset every turn since it became a reserved flag in "Quill C". This problem can be solved reusing flag 21 (that controls finding the jar) for the gun also, since the jar is a requirement for accessing the gun location. Both cases are originally implemented as follows:
    7a18: GET JAR:
    7482: AT 112 ;at location 112?
    7484: EQ 21 1 ;flag 21=1?
    7488: MESSAGE 99 ;"Sorry, but you've had your quota of miracles."
    748a: DONE

    7a1c: GET JAR:
    748c: AT 112 ;at location 112?
    748e: ZERO 21 ;flag 21=0?
    7491: CREATE 12 ;create jar
    7493: GET 12 ;get jar
    7495: PLUS 21 1 ;set flag 21=1
    7498: PLUS 30 3 ;increase score
    749b: MESSAGE 98 ;"Miraculously, your wish is granted."
    749d: DONE

    The following patch fixes this problem:
