Princess of Dark is a relatively early graphic text adventure that was being worked on around 1993, but seems to have been abandoned fairly early on.
It isn’t really playable, though you can enter a few lines to get some amusing replies. Try for instance:
- kiss my ass
- shit game
- i love susi
It would be interesting to hear if anything more was done with the game and if something playable was ever produced, and who it was for too.
