Retro Replay Review

Gameplay

Commander Keen 1: Marooned on Mars offers a delightful blend of exploration and platforming that remains accessible to newcomers while still presenting a satisfying challenge. At its core, you navigate a top-down map of Mars to select levels and then dive into side-scrolling stages where precise timing and careful jumps are essential. Each level hides one of the four rocket parts you need to repair your Bean-with-Bacon Megarocket, encouraging thorough exploration rather than a simple sprint to the exit.

The controls are tight and responsive: Keen can walk, duck, and fire his trusty raygun at the myriad of Martian enemies. When the going gets tough, the pogo stick becomes your best friend, enabling you to bounce over dangerous pits and reach high platforms that would otherwise be inaccessible. Finding keycards to open locked doors or collecting score items for extra lives adds an extra layer of strategy—you’ll often backtrack to previous areas once you have the right tools, giving each level a satisfying sense of progression.

Death comes swiftly—one touch from a hazardous creature or an ill-timed fall sends you back to the map screen and costs you a life. Yet the design is fair: levels are carefully laid out so that you learn enemy patterns and level quirks rather than feeling cheated by unseen traps. The game’s balance of risk and reward keeps you engaged, and the modest difficulty curve ensures that both young players and veteran platformers can find reasons to keep coming back for more.

Graphics

Visually, Commander Keen 1 is pure early ’90s charm, featuring bright, block-colored sprites that stand out cleanly against solid background hues. The Martian environments range from dusty red plains to alien city interiors, each with distinctive tilesets that keep exploration visually interesting. Though the color palette is limited, id Software’s designers used contrast effectively so enemies and key items are always clearly visible.

The character animations are simple but expressive: Keen’s jaunty run cycle and pogo-bounce are immediately recognizable and give him a sense of personality despite his diminutive size. Enemy sprites—from harmless Yorps waddling about to more menacing Trogs—move with enough variety to feel alive without overtaxing the hardware of the era. The top-down map uses a different visual style entirely, providing a welcome change of pace and giving you a clear sense of where you’ve been and where you need to go.

Sound design is minimalist but fitting. The bleeps and bloops of your raygun, the springy “boing” of the pogo stick, and the simple jingles for collecting items all contribute to the game’s playful atmosphere. While there’s no voice acting or orchestral soundtrack, the chiptune melodies are catchy enough to linger in your memory and reinforce the retro aesthetic that makes Marooned on Mars so endearing.

Story

Billy “Commander Keen” Blaze may only be eight years old, but his genius-level intellect shines through in this lighthearted sci-fi romp. The premise—Keen’s Bean-with-Bacon Megarocket breaks down and the sneaky Vorticons steal its parts—sets up a straightforward rescue mission that never feels overwrought. The simple “find the missing parts” narrative is communicated efficiently, leaving room for the player’s imagination to fill in the details.

Despite the brevity of the storyline, the game’s presentation—complete with humorous in-game texts and the lofty title of “Commander”—gives it a playful charm. You can sense the tongue-in-cheek tone in every level flier and each interaction with an alien adversary. This breathes life into what could otherwise be a dry fetch-quest, ensuring that every rocket part you retrieve feels like a small victory in Keen’s grand adventure.

For modern players, the story’s nostalgic appeal is undeniable. While there are no branching dialogues or deep character arcs, the core narrative structure has aged well: it’s concise, easy to follow, and never interrupts the gameplay flow. If you’re looking for a platformer with a memorable protagonist and a whimsical sci-fi backdrop, Commander Keen 1 delivers exactly that without any unnecessary filler.

Overall Experience

Commander Keen 1: Marooned on Mars stands as a landmark in early PC gaming, and its enduring appeal lies in its perfect marriage of simple storytelling, engaging platform mechanics, and charming visuals. Playing it today feels like unearthing a piece of gaming history—one that retains its playability and sense of fun decades after its initial release. Whether you’re exploring the Martian map for the first time or revisiting it for old-school nostalgia, the game’s balance and design hold up remarkably well.

Replay value comes from mastering levels you once found tricky, hunting for every secret nook, and aiming to beat your best lives or high-score runs. While the technology behind it is dated by modern standards, the core design philosophies—tight controls, clear level goals, and satisfying enemy encounters—remain relevant. For those interested in seeing where the side-scrolling PC platformer began, Commander Keen 1 is essential.

In conclusion, Marooned on Mars is more than a retro curiosity; it’s a legitimately fun platformer that can still stand alongside contemporary indie titles. Its easy pick-up-and-play nature makes it suitable for players of all ages, and its historical significance in the evolution of PC gaming is undeniable. If you’re in the market for a bite-sized, challenging adventure with plenty of old-school charm, Commander Keen 1 will rocket you straight back into a golden age of gaming.
