Kill It With Fire

Every so often a game arrives that could have been pitched in four words and needed nothing more. Kill It With Fire is that game. You are a newly licensed arachnid exterminator. There is a spider behind the cereal boxes. You have a flamethrower. The rest is arithmetic.

Developed by Casey Donnellan Games LLC — effectively a one-person operation — and published by tinyBuild, the studio that has built a business out of finding oddball indies with a viral hook and pointing a megaphone at them, Kill It With Fire launched on August 13, 2020 into a market saturated with survival crafting and open-world checklists. It ignored all of it. What it offers instead is a first-person immersive-sim skeleton stripped down to a single verb: destroy this room until the arachnid stops existing.

The market positioning is unusually honest. This is a $2.59 impulse buy designed around a clip you’d send a friend — the moment you empty a shotgun into a bookshelf, miss, and watch the spider sprint across the ceiling toward your face. tinyBuild understood that. The game is short by design and priced accordingly, and its commercial success came from the exact thing critics of “content value” tend to punish: it does not overstay.

The reception numbers back the strategy. Steam’s rating sits in overwhelmingly positive territory, and the game holds a Metacritic score of 68 — respectable rather than rapturous, which tracks with a title this narrow. The mobile story is considerably rougher, and this review gets there, because the gap between those versions is the most interesting critical fact about this release.

• Escalating Absurdity Arsenal: You begin with a clipboard and a folded newspaper. You end with throwing stars, C4, SMGs and a flamethrower. The joke is the escalation curve itself — the weapon tier list is a punchline delivered over a few hours.
• Propagating Fire Simulation: Flames spread across carpet, curtains and upholstery with genuine physical logic. This is not a particle effect. It is a systemic mechanic, and collateral damage is scored rather than penalized.
• The Arachnid Tracker: A handheld device that narrows a spider’s location without pinpointing it. To close the gap, you must physically dismantle the room — every object grabbable, every object breakable.
• Eight Behaviorally Distinct Species: Some flee. Some leap directly at the camera. The difference between those two behaviors is the difference between a puzzle and a jump scare.
• Deadpan Conspiracy Layer: Hidden documents scattered across suburban homes, offices, a strip mall and a research facility build a straight-faced plot that never once winks. Optional objectives, secret weapon unlocks, an endgame Arachno-Gauntlet horde mode and a secret ending reward the completionist.

The Gameplay Loop

The core loop is a search-and-destroy cycle so clean it reads like it was reverse-engineered from a design textbook. Enter a room. Consult the tracker. Get a rough heading. Start opening things. The spider bolts. Panic. A thrown chair. The room is now on fire.

What makes it work is the deliberate imprecision of the tracker. A lesser designer would have given you a waypoint marker and called it a day. Donnellan gives you a proximity signal — enough to narrow the search to a sofa, not enough to tell you which cushion. That single restraint is what converts a fetch quest into tension. You are always slightly wrong about where the thing is, and the act of confirming your guess is inherently destructive. The game has no separate “destruction mode.” Destruction is the search.

This is the sly bit of design that makes the whole thing work. Most sandbox games treat physics as a toy box bolted onto an objective structure. Here the physics are the objective structure. You cannot progress without wrecking, and wrecking generates the information you need. Cause and effect are welded together.

The Fire Simulation

The flamethrower deserves specific credit, because propagating fire is hard to get right and easy to fake. Most games render fire as a decal that expires on a timer. This one spreads with a logic you can learn and then abuse — light a curtain, and it takes the carpet; the carpet takes the couch; and the spider you’ve been hunting comes sprinting out of the inferno directly at your face.

That emergent sequencing is the entire value proposition. The best moments in Kill It With Fire are not authored. They’re the product of a simulation doing its job while the player flails.

The Tension Is Real

One thing the marketing undersells: this game is scary. Not in a horror-design sense, but in a hardwired, lizard-brain sense. The leaping species are built to trigger a startle response that no amount of ironic distance protects against. Arachnophobes should treat the title as a content warning rather than a joke — the game includes no meaningful accessibility option for spider models, which reads as an oversight rather than a stylistic choice. Plenty of studios have shipped arachnophobia modes since. This one hasn’t.

Where It Runs Thin

Now the criticism, and it’s the same criticism the Steam community has been leveling for years: the structure repeats. The environments change — suburban home, office, strip mall, research facility — but the verbs do not. By the fourth stage the tracker’s behavior is internalized, the top twelve hiding spots are known, and the discovery curve flattens into routine. The optional objectives and hidden unlocks paper over this reasonably well, but they’re side dressing on a loop that has already shown you its hand.

The total runtime is a few hours. Completionists chasing the secret ending and the Arachno-Gauntlet stretch that further, but nobody should walk in expecting a campaign. The honest framing is that this is a good comedy short, not a feature film, and the Steam reception suggests most buyers arrive with exactly that expectation and leave satisfied.

The physics themselves occasionally betray the fantasy. Objects sometimes fuse to geometry, spiders can clip into surfaces the tracker insists they occupy, and there are rooms where the simulation’s ambition outruns its collision handling. On PC these are texture, not failure. On mobile they become something worse.

The art direction is a smart, low-cost solve: stylized low-poly interiors with flat, saturated color and heavy readability. Nothing here is chasing photorealism, and that’s the right call — a realistic house full of realistic spiders would be unplayable for most of the audience, and the polygon budget goes instead to object count, which is the metric that actually matters when the design demands hundreds of grabbable, breakable props per room.

The result reads as toy-like without reading as cheap. Fire is the visual centerpiece and the lighting sells it, throwing warm dynamic light across the flat surfaces in a way that makes a burning living room striking.

A low-poly game of this scope is light on hardware by design, though the physics load spikes when a room reaches critical mass — a dozen burning objects, furniture in flight, the fire sim propagating across three surfaces at once — and that is where weaker machines would be expected to feel it.

This is where the review splits into two verdicts.

Steam is the definitive version, full stop. Mouse aim is essential to a game whose central skill is snapping a crosshair onto a spider moving erratically across a wall. Keyboard-and-mouse grabbing and throwing has the tactile precision the design assumes. Everything below is measured against it.

Nintendo Switch is a reasonable compromise. Analog aim costs meaningfully in the moments that matter most — the panic-tracking of a fleeing species across a ceiling is simply harder on a stick — but the content is intact and the game’s forgiving hit detection absorbs some of the loss. The obvious caveat is hardware: a propagating fire simulation across a room full of dynamic objects is precisely the workload a Switch struggles with, and heavy scenes are where frame pacing would be expected to suffer. We rate it the portable option, not the preferred one.

iOS is the one to avoid. The App Store rating tells the story: 3.8 out of 5 from 4,713 ratings, against an overwhelmingly positive Steam reception. That is not a platform-bias gap. That is a port problem. The consistent complaints are imprecise touch controls, a reduced weapon set versus the PC build, and altered physics that undercut the exact simulation the game is built on. Worse, there is a long-standing progression-blocking bug on the “Paper Trail” level where toilets cannot be destroyed — a hard wall in a paid product that has gone unpatched. The absence of updates is the real indictment. And the Android version has been delisted from Google Play and no longer resolves at all, which tells you where mobile sits on the maintenance priority list.

A touch port of a physics comedy was always going to be difficult. Shipping it and then walking away is a choice.

Kill It With Fire makes the case that a single well-executed idea can carry a game. Donnellan took a premise most studios would have burned on a five-minute jam game and built a real system underneath it — a search mechanic that requires destruction, a fire sim that generates its own punchlines, and a difficulty curve made of escalating firepower rather than escalating enemy health bars. The repetition is real and the runtime is short, and those flaws matter; the game knows both things about itself and prices accordingly, but they keep it from greatness.

The asterisk is mobile. The iOS version isn’t a lesser edition of a good game; it’s a different, worse game wearing the same icon, and the unpatched Paper Trail blocker means some players paid for a product they cannot finish. Buy it on Steam. Take it on Switch if portability matters more than precision. Skip the phone entirely.
