The Gunk

Image & Form spent a decade building a reputation on 2D precision. The SteamWorld games — Dig, Dig 2, Heist, Quest — were tight, confident, genre-hopping things made by a studio that clearly understood pacing better than most outfits ten times its size. The Gunk is what happened when that studio, folded into the Thunderful umbrella, went 3D for the first time. It launched as an Xbox console exclusive and a day-one Game Pass title, which is a specific kind of positioning: the mid-budget, five-hour, “you’ll play this because it’s already paid for” slot. On Steam, where it arrived April 29, 2022 at $24.99, that context evaporates. The math gets harder.

You play Rani, half of a two-person space hauling operation that is one bad contract away from insolvency. She and her partner Becks set down on an unlogged planet expecting a quick score. What they find is an ecosystem being strangled by a parasitic sludge — the gunk — and Rani’s wrist-mounted Power Glove turns out to be very good at eating it. Suck up the sludge, watch the smothered flora explode back into color, and the world literally opens: vines become ladders, stumps become platforms, dead ground becomes a path.

The design’s central tension is instructive. The restoration loop is built to produce a feeling — the satisfaction of a cleansed, blooming world — and by most accounts it does. But judged as a system, it’s a single verb repeated with bigger numbers attached. That distance between mood and mechanics is exactly the review.

• The Power Glove vacuum: A wrist-mounted suction tool that inhales gunk deposits, hostile spores and loose resources. Its design leans on weight, audio punch and physical feedback — the single best-executed thing in the game.
• Restoration-as-traversal: Cleansing an area isn’t cosmetic. Dormant vegetation regrows in real time and becomes the level geometry you climb, jump and route through. Cleaning is the level design.
• Biomass economy and upgrades: Purified gunk refines into materials that improve suction strength, combat output and scanner range, delivered through a compact upgrade bench rather than a sprawling skill web.
• Scannable ecology and ruins: A codex-driven mystery about a vanished civilization, unlocked by scanning plants, fauna and architecture as you pass.
• A two-hander radio drama: A continuous, well-written conversation between Rani and Becks about trust, money and what you owe a place you’re about to strip. Fiona Nova’s performance as Rani is the emotional spine of the whole thing.

The Gameplay Loop

The vacuum is why this game works at all: the design of the suction is excellent on paper and clearly executed with care — the gunk stretches and resists before it tears loose, the glove’s whine escalates, a deposit gives way with a wet snap. It’s the same itch that carried PowerWash Simulator to a mass audience, but here it’s married to something more ambitious. Cleaning doesn’t just reveal the world; it builds it. A wall you can’t climb becomes climbable because you cleared the rot beneath it. That’s a real idea, and for the first stretch it’s close to magical.

Then the loop stops developing. This is the game’s central failure, and it isn’t subtle. The glove in hour five behaves almost exactly like the glove in hour one, just with bigger numbers attached. The upgrade tree — improved suction, extended scan radius, sturdier combat — is a set of quality-of-life multipliers, not a set of new verbs. Compare this to a Metroidvania’s tool progression, or to Image & Form’s own SteamWorld Dig 2, where each acquisition rewrote how you moved through space. Here, nothing rewrites anything. The core interaction is fully expressed in the tutorial.

Combat and Puzzles

Combat is the weakest pillar. Gunk-mutated creatures approach, you suck the vulnerable node off their body, you finish them. Encounters are speed bumps dressed as fights — friction that exists to interrupt the vacuuming rather than to test anything. The enemy variety is thin, the arenas are undesigned, and the game never asks you to think under pressure. In a five-hour title this is survivable. It is also a missed opportunity, because a vacuum is an inherently interesting combat tool and the game seems slightly embarrassed to use it as one.

The puzzles fare marginally better but land in the same place: environmental, obvious, and solved the instant you see them. Route a plant’s growth, clear a blockage, weigh down a pad. There is no moment where The Gunk trusts you to be confused. Given how much of the game is spent looking — at ruins, at flora, at the middle distance — a little more interpretive difficulty would have cost nothing.

The Thematic Contradiction

Here’s the thing the marketing doesn’t talk about. The Gunk is a story about the ethics of extraction, in which Rani’s arc is learning that a planet is not a resource. And the mechanical loop asks you to hoover up every last scrap of biomass on the map and refine it into personal upgrades. You are rewarded for total, exhaustive harvesting of the environment you’re supposedly saving. Becks’s greed is the thing the script criticizes, and the achievement list is a checklist for behaving exactly like her.

This reads as unintentional rather than ironic — a game that wrote a good screenplay and then bolted a conventional collectible economy underneath it without checking whether the two agreed. It’s the sort of seam a longer development cycle sands off — and it’s the reason the story lands emotionally but not thematically.

Pacing and Structure

Linear, gated, and honest about it. There’s no map, no fast travel, no busywork. For a five-to-six hour campaign that’s the correct call, and the structure is tight enough that the repetition has room to breathe — though a static mechanic over five hours is a lot of static mechanic, and the final act is where that shows. The absence of padding deserves real credit. Very few studios have the discipline to end a game when it’s finished.

The art direction is the reason this game has any reputation at all. The palette contrast is superb: bruised ochre and grey-purple sludge against the electric bloom of restored plant life, so that every cleanse reads as a visual reward before it reads as a mechanical one. The alien flora is hand-designed rather than procedurally scattered, and it shows — silhouettes are legible, biomes are distinct, and the ruins carry a specific melancholy that the codex text mostly lives up to. The score is understated and atmospheric, doing quiet, unshowy work.

The caveat is technical. A game this dependent on moment-to-moment tactility is uniquely punished by any dropped frame at the exact instant a gunk deposit tears free, and a 3D action game of this scope on PC is the kind of release where hitching and scattered bugs are a reasonable thing to check recent feedback on before buying. On modern hardware it’s a nuisance, not a dealbreaker — but it’s the wrong nuisance for this particular game.

Small note on the storefront: four screenshots. For a game whose entire pitch is visual transformation, that’s an act of self-sabotage. This is a title that sells itself in motion and the Steam page barely tries.

The Gunk was built controller-first and it doesn’t hide it. Aiming the suction cone is a right-stick action with generous assist, climbing is contextual and forgiving, and the whole traversal grammar assumes analog input. Play it with a gamepad. Mouse and keyboard works — mouse aim is arguably more precise for grabbing distant deposits — but the climbing and ledge-transition system was tuned for a stick and reads as stiffer under WASD.

On Steam specifically, this is a clean, low-maintenance port with cloud saves and a straightforward achievement list that mostly rewards scanning and collectible sweeps rather than skill. The short runtime, contained scope and controller-native design make it an obvious handheld candidate for a device like the Deck; check the current compatibility badge before committing.

The pricing question is entirely a Steam question. On Game Pass, The Gunk was positioned as a delightful weekend. At $24.99, five hours with a static mechanic asks you to value mood over content. Buy it on sale. That’s not a hedge, it’s the actual recommendation.

The Gunk is a very good idea executed with real craft and almost no ambition beyond its first hour. Image & Form built a loop that most studios would have spent an entire game escalating, and then chose to write a screenplay instead. The screenplay is good — Rani and Becks are one of the better two-hander relationships in recent indie sci-fi, and the design of the glove is close to unimprovable. But a five-hour game whose central verb is identical at minute 300 to minute 3 has left something on the table, and the gap between the game’s warm reception and its thin systems is the sound of that shortfall being argued about.

The appeal is real, though, and it deserves respect. This is a game built to make people feel good. It’s short, kind, beautiful, mechanically honest, and it ends before it overstays. In a market drowning in 60-hour content treadmills, “finished it and glad I did” counts for something. Just don’t pay full price for the privilege.

Mixed — A gorgeous, gentle, mechanically undernourished game. Wishlist it, wait for the discount, then enjoy every minute.
