Ambrosia Sky Review: A Timely Sci-Fi Cleanup That Asks Why People Stay

Soft Rains' debut title Ambrosia Sky arrives on Windows PC as a complete experience after an unusual two-part release that began in 2025. The first-person sci-fi game tasks players with cleaning up a fungal contamination called the Cluster across an asteroid colony, but its real subject is far more human: the question of why people stay when disaster strikes. "Why don't they just leave?" the reviewer asks, echoing a refrain heard during hurricanes and pandemic lockdowns alike. Ambrosia Sky refuses the easy judgment that question implies, instead building its entire narrative around the complex, deeply personal reasons communities hunker down.

For players who have spent years watching real-world crises reduced to statistics and political talking points, this game offers something rare in the medium: a cleanup simulator that treats every victim as a story worth uncovering. The gameplay loop of blasting fungus with a high-powered spray gun while tethered to zero-gravity environments feels fresh precisely because it serves that empathetic core. Blackbird Interactive, the studio behind Hardspace: Shipbreaker, assisted on the final release, and that DNA shows in the best zero-gravity sequences. The result is a game that feels timely without being preachy, even when its ambitious storytelling occasionally tangles itself in knots.

What Is Ambrosia Sky?

Developed by Soft Rains and released on Windows PC in 2025, Ambrosia Sky blends immersive sim elements, first-person puzzle design, and a narrative-driven structure into a genre hybrid the reviewer aptly describes as Metroid Prime meets Powerwash Simulator. You play as a cleaner dispatched to board abandoned ships overtaken by the Cluster, a fungal infestation that has claimed an asteroid colony. The game was originally conceived as a three-part episodic release. Players who missed Part One last year may be better positioned, as the complete package appears to deliver a sharper, more cohesive experience than the fragmented original launch.

The game was reviewed on Windows PC using a prerelease download code provided by Soft Rains. At its heart, Ambrosia Sky is about extraction — not just of fungal growth, but of memory. Each ship you board contains the bodies of those who didn't evacuate, and your spray gun becomes a tool for both cleanup and archaeology. The premise resonates differently now than it might have in 2020; we are still sorting through the aftermath of a global pandemic, and the game's insistence on humanizing the dead feels like a quiet act of resistance against the dehumanization that follows every major crisis.

Gameplay and Mechanics

The core loop revolves around your chemical spray gun, a tether for movement, and the occasional zero-gravity environment that turns corridor cleaning into three-dimensional navigation. Carving paths through poisonous hallways delivers genuine satisfaction, especially when the level design opens up into interconnected puzzles. One standout sequence has you clearing the exterior of a fungus-wrapped ship while floating in zero gravity, rerouting power systems in a way that evokes the tense, methodical ship deconstruction of Hardspace: Shipbreaker. Another late-game level sends you through a labyrinthine vessel hunting for specimens, and these moments represent the gameplay at its fullest potential.

Tension emerges naturally from the fungal ecosystem itself. Cutting seeds off growths yields suit upgrade parts, but a misplaced shot can detonate explosive plants and set entire sections ablaze. Part Two introduces corrupted vines that can only be removed by locating and destroying their source, adding a welcome puzzle layer to the cleanup. DNA extraction from victims serves narrative purposes, opening up memories that explain why each person stayed behind. The movement feels weighty and deliberate, and the tether becomes second nature quickly, making zero-gravity sections feel liberating rather than disorienting.

Visuals, Audio, and Performance

Ambrosia Sky presents a hard sci-fi aesthetic that prioritizes readability over spectacle. Ships feel lived-in before the Cluster took hold — personal effects, workstations, and scattered communications paint a picture of interrupted lives. The fungal growth itself is the visual star, spreading across surfaces with organic menace that reacts satisfyingly to your spray. Zero-gravity exteriors offer striking vistas of the asteroid colony against deep space, though the game's scope remains intimate rather than expansive. Performance on Windows PC was stable throughout the review period, with no notable frame drops during the more particle-heavy cleanup sequences.

Audio design reinforces the isolation of the work. The hiss of your spray gun, the wet crunch of dissolving fungus, and the ambient hum of derelict ships create a soundscape that feels industrial and melancholic in equal measure. Voice logs and memory fragments are well-acted, grounding the more surreal narrative beats in human grief and determination. The game doesn't push technical boundaries, but its art direction serves the story — every visual and audio choice reinforces the theme of careful, respectful excavation.

What Doesn't Work

The upgrade system is the game's most conspicuous weak point. Various spray additives — electrical, flammable, and other specialized chemicals — open up as you progress, but the reviewer struggled to find situations where they outperformed the basic spray. The game presents itself as an immersive sim offering player agency in cleanup approach, yet never designs obstacles that demand anything beyond the default tool. This renders the upgrade tree functionally decorative, a collection of solutions in search of problems that never materialize.

Combat suffers from a similar identity crisis. A single enemy type appears in Part Two, but its inclusion feels shoehorned into an experience that never commits to being an action game. The enemy encounters are rare, simple, and disconnected from the cleanup mechanics that define the rest of the experience. Meanwhile, the narrative's ambition occasionally outpaces its execution. Threads involving religious cults and corporate conspiracies drift in and out of focus, and some of Part One's most intriguing cliffhangers feel unresolved — possibly casualties of the decision to condense a three-part plan into two. The fragmented storytelling can leave players uncertain whether they missed important details or if the game simply didn't deliver them.

Ambrosia Sky lands as a fascinating, flawed piece of sci-fi that asks the right questions even when it fumbles some answers. Its empathetic core — the insistence that every person who stayed behind had a reason worth hearing — elevates what could have been a simple cleanup simulator into something that lingers. The upgrade system and combat feel like vestigial limbs from a design document that imagined a different game, but they don't undermine the experience's emotional center. For players who value narrative ambition and mechanical novelty over polish, this is a journey worth taking. The game is available now on Windows PC via Steam.
