Yes indeed! The sequel - Dagger of Amon Ra - was posted previously. But I just love the artwork for the first game. It’s one of my favorite Sierra covers.
This game was complicated, much more complicated than the average Sierra title. There were timed events, things you could easily miss, and if you didn’t do a perfect playthrough, you may not see the better ending. So you really had to play this multiple times, have detailed notes and schedules, and figure out the best way to move through the game.
It had some awesome random (terribly so) deaths, though - even more random ones than your usual Sierra game. Almost immediately, you could be killed by taking a shower, falling through the stair railing (for no reason), walking under a chandelier which will randomly fall on you, get cut open by a suit of armor, etc.
Still, I have fond memories of it.
