Thank you, that means so much to us that you enjoyed the game as much as you did :D
It's really wonderful seeing so many Shadowgate fans out there that appreciate this niche sub-genre. I also grew up on these games and eagerly anticipated a fourth NES game in the series, which I predicted would be on a space ship, but it never happened, so we figured why not make it ourselves.
Have you played Deja Vu or Uninvited for the NES? Spectacle is actually an unofficial prequel to Uninvited, so if you like references and easter eggs, than that game has plenty!
Thanks again and we really hope you enjoy Spectacle. It would be awesome to see you make a tribute to the genre. There's a few devs out there currently making "shadowgate"-style games, so it would be great to bring this sub-genre back full swing :D
