Moonmist (1986)

A haunted Cornish castle offers a gentler-looking introduction to watching the night unfold. Dinner, guests' movements and later appearances make waiting and choosing where to investigate meaningful; TIME reports the hour, and the story pauses while you consider your next command. Four colour-selected variations change the mystery, so clues from one should not be assumed to solve another. SAVE and RESTORE let you return to an earlier part of the evening. It is approachable by Infocom standards, with treasure-hunt riddles alongside the detective work.
