De Ja — About this game
Follow an archaeologist through a mystery built from conversations, objects and changing locations. Each screen offers verb commands such as examining, talking, asking, taking and using, with further choices appearing when the selected action needs a subject. A scene often advances only after the useful information has been gathered, so an apparently finished conversation can still leave an important detail undiscovered. Inspect objects before trying to use them elsewhere, and revisit a person when another event supplies a new question. The adventure's character encounters and mature humour provide the setting around its command-based investigation.
