Deja Vu is a point-and-click style game of adventure and exploration originally developed by a small team at ICOM Simulations for the Macintosh. This was the first game in their "MACventure series," as the games have been affectionately dubbed. The original lineup consisted of Deva Vu, Unintived, Shadowgate, and Deja Vu 2. All but the Deja Vu sequel were later ported to the NES by Kemco.
The NES version features a fresh coat of paint and some tweaks with the interface, as well as some fun music. Although Deja Vu was the only MACventure title to receive a sequel during the original development, Shadowgate is the one to have persisted. Sadly, Deja Vu has largely fallen out of the public consciousness.
But enough about all of that extended universe stuff. This is a fun little game on its own. I remember reading about this in Nintendo Power when I was a kid, but never got around to renting it. Having recently rediscovered it, I envy Ace's amnesia…since now I can no longer play this game for the first time.
