PerlNotes? Is there such a program?

[elfs]

I started out on a castle spire, talking to a blocky, pixelated fellow who told me, in 1980's style white word ballons with half-millimeter blocky black borders, that this was a program called PerlNotes and that I should work my way down to the dungeons to uncover how the program works, write it myself, and make a million dollars.

That has to be the strangest dream I've had recently.
