EVERY screen in wanderer is soluble exactly as given, using the
source exactly as given. Even screen 13.

I cheated in the usual way - by keeping a dump of input
keystrokes and reusing them up until just before the previous
mistake. Even so, it took many false attempts and failed
strategies to get number 13.

There is one more bug in the source. After completing screen 13,
you should get killed by a non-existant screen. However, the
fclose call in read.c causes a core dump by being applied to a
null pointer.

      if(fscanf(fp,"%*s\n%d",maxmoves) != 1)
       *maxmoves=0;
      };
- fclose(fp);
  return (fp == NULL);
  }
--- 21,26 -----
      if(fscanf(fp,"%*s\n%d",maxmoves) != 1)
       *maxmoves=0;
+     fclose(fp);
      };
  return (fp == NULL);
  }
***************

With this one fix only to the source, there is a run to
completion with a final score of 10144. This run collects every
trap, diamond and packed earth from every screen, except for two
packed earths on screen 6, which i think have to be left to
protect you from arrows.

The 13 screens are very clever, although i suspect the solution to number
13 is due not so much to clever design, as to good fortune. Good game.
I look forward to seeing a new version with a larger screen, and without
the feature that lets sprites occasionally eat up other objects.

Regards, Chris Stuart.

PS. Here is the final bit of output (by way of evidence).
