This appears to be a review copy of a
game sent to publishers. It is not
immediately playable; it displays the
title screen that flashes "EVALUATION
COPY" then exits to a BASIC prompt.

The startup program is still in memory,
so let's take a look:

]LIST

...
 30 V = 1: GOSUB 90:A$ = "AN ALL-
     TEXT ADVENTURE":V = 3: GOSUB
     90:A$ = "VERSION 1.1.0":V =
     4: GOSUB 90:A$ = "(C)1985-7
     BY ERIC A. SEIDEN":V = 7: GOSUB
     90
 40 V = 12:A$ = "EVALUATION COPY"
     : FLASH : GOSUB 90: NORMAL
 50 A$ = "ALL RIGHTS RESERVED":V =
     8: GOSUB 90:A$ = "PRESS A KE
     Y TO CONTINUE":V = 20: GOSUB
     90: CALL 768: POKE  - 16368,
     0
 60  END
 70  PRINT  CHR$ (4)"BLOAD DARSYS
     .SYSTEM,A$2000,TSYS": POKE  -
     16304,0: POKE  - 16297,0: POKE
      - 16300,0: POKE  - 16302,0:
      FOR A = 1 TO 3000:J =  PEEK
     ( - 16384): IF J > 128 THEN
     A = 9999
...

Ah, there's your problem right there,
sir. The program ends on line 60
instead of not ending on line 60.

...game loads and plays...

Quod erat liberandum.
