The game is perhaps best described as a cross between surrealist painters Salvador Dali and Rene Magritte, with a plot that is no less strange
It's not a game I remember but can imagine it being a challenge my husband may have enjoyed...he was a clever clogs.
The video clips on You tube don't show much...
I don't think "Blue Ice" was a big seller as it was so unusual and unlike any other game at that time.
As you say, the video clips don't show much and can't give any real sense as to how playing the game felt.
In the box, there is a small leaflet of obscure poems written for the game which might mean something if one could understand them.
In terms of adventure games from that era which were trying to do something different, the best would be Lucasfilm Games' "Loom" from 1990. Experimental for its time, and a very good storyline. It is regarded as one of the best adventure games written. The version on Steam is not the original version which was superior. Of course, the graphics and sound are primitive by modern standards. Who knows, one day someone might publish a version for modern devices. There was talk of a sequel but that never happened,
Lucasfilm Games wrote some very good adventure games including the Monkey Island series. One of them was the 1995 "The Dig" which was a science fiction one. Interesting background behind that was that Steven Spielberg had previously envisaged the storyline for a film but didn't go ahead as it would have been too expensive,
