The game is presented from a third-person perspective with animated, single-screen scenes. Roger explores the Xenon Orbital Station and later other locations, collects objects, talks to characters, and enters commands such as examining, taking, using, or talking.

Progression is mostly puzzle-based. The player must discover useful items, interpret environmental clues, and solve situations in the correct order. The game includes dangerous areas and many possible deaths, so saving frequently is important. There is no combat system or character-level progression.

Save before entering unfamiliar rooms, trying an unusual command, or approaching an apparently dangerous object.

• Examine every scene and item, and try common parser verbs such as look, take, use, open, and talk.
• Keep important objects rather than discarding them; several puzzles depend on using an item later.
• Treat suspicious scenery as potentially lethal and revisit locations after major discoveries.
