How it plays
How does Commander Keen in Goodbye, Galaxy!: Episode IV - Secret of the Oracle play?
The game uses a side-scrolling perspective across an overworld map and individual platforming stages. Keen must reach each stage’s exit while collecting items, finding keys, avoiding hazards, and dealing with hostile creatures.
The player can jump, use a pogo stick, or fire a limited raygun. Stages contain secret areas, switches, moving platforms, and bonus items. Completing selected levels advances the story, while the map allows some freedom in choosing the next destination.

- Explore corners and unusual walls for secret rooms and valuable items.
- Conserve raygun ammunition and use the pogo stick when a jump requires extended vertical control.
- Mark completed map locations so you can return to missed exits, keys, or bonuses.
