The game uses a first-person point-and-click adventure perspective within static illustrated scenes. Roger explores spacecraft, planets, and other locations, examines objects, talks with characters, collects items, and combines or uses them to solve puzzles.

Progression follows a sequence of story locations and set pieces aboard the G.E.N.E. and elsewhere. The player must investigate clues, manage inventory items, choose suitable dialogue or actions, and occasionally avoid hazards that can kill Roger. Saving often is important because some failures are immediate and the game expects experimentation.

Examine every new scene and use the interface on suspicious objects before leaving. Keep unusual items rather than discarding them, and revisit earlier locations when a new clue or tool changes what can be done.

Save before experiments, conversations, and hazardous-looking sequences. Sierra adventure logic can require a particular item or action order, so record clues and try combining inventory items only when their functions or descriptions suggest a connection.
