how to kill a fly [ H2KAF ]

A corporate flesh object with no words of its own

how to kill a fly [ H2KAF ]'s premise is stated with unusual bluntness right on its store page: you are "a corporate flesh object with no way to speak on your own trying to pose as a human by mimicking what other people say," serving the corporation that owns you while trying to complete your assignment. That framing sets up the game's entire mechanical identity — rather than free dialogue options, you survive by knocking on doors, listening to what the people behind them say, and repeating fragments of it back to other characters to convince them you belong. One reviewer sums the resulting genre blend up neatly as "a dystopian cyberpunk walking puzzle PnC akin to Observer_," and that comparison recurs often enough across the review base to read as the closest available shorthand for what the game is actually doing.

A world built from plastic, green light and corporate rot

Reviewers are remarkably aligned on the strength of the presentation. One writes plainly that the moment you open the game "you can immediately tell it was made with passion and creativity," citing the setting, sound design and dialogue as all working together toward something that feels "unwelcoming, yet genuine." Another, drawing the game into more overtly political territory, compares its "critique of dehumanizing technological progress" and its saturated green colour palette to Cruelty Squad, framing both games as sharing a specific strain of corporate-dystopia satire that's rare even within the wider cyberpunk genre. A third reviewer describes the world as conveying something "incredibly rich" and "extremely immersive" despite the game's limited physical space, crediting careful writing and sound design for making a small handful of locations feel like a complete, lived-in setting rather than a demo-sized slice of one.

Mimicry as a puzzle, and where it goes wrong

The dialogue-mimicry system is the game's clear point of mechanical identity, and most reviewers treat it as a success: one calls it a genuinely new idea, noting "we don't really have 'listen to people and repeat their lines to progress' type games," and several others describe finding the right lines to repeat as satisfying rather than tedious once its internal logic clicks. The most detailed critical account in the review base pushes back hard on that framing, though, describing a puzzle structure that "presents you with too many choices and punishes you for choosing the wrong one," with correct answers that can be "difficult, I'd even say impossible, to figure out," compounded by having to first locate the right conversation at all "like a literal needle in a haystack." That same review reports a specific, unwarned soft lock: exploring a particular part of the world permanently removes access to an associated side quest, with the game giving no signal in the moment that the choice is final. It's a sharp, specific complaint rather than vague frustration, and worth weighing seriously even though it comes from a minority position within the review base.

An assist mode that reviewers say genuinely helps

Set against that difficulty complaint, multiple reviewers specifically credit a built-in assist mode with meaningfully lowering the barrier to entry. One writes that "having an assist mode made a world of difference for me," framing it as something to toggle on the moment a player feels stuck rather than a setting to feel bad about using. Several self-described less puzzle-literate reviewers make a point of saying they still recommend the game despite finding its choice-based structure genuinely difficult, explicitly crediting the assist option and the strength of the surrounding writing for keeping them invested regardless. Steam's own category listing confirms the feature is a first-class, launch-day inclusion rather than a post-launch patch, alongside custom volume controls and support for playing without timed input — an accessibility baseline that's unusually considered for a small, singular-vision narrative release.

Short, and built to reward a second look

Several reviewers frame the game's short length as a feature rather than a shortcoming, describing runs completed in well under two hours and specifically praising how tightly the writing is edited as a result — one describes finishing a full run in "12:47, +/- ~2 minutes," timed against the game's own autosave. That same reviewer, along with several others, explicitly returned for repeat playthroughs after finishing the demo, chasing missed dialogue branches, alternate outcomes and the game's full achievement list rather than treating a single clear ending as the end of their engagement with it. That pattern — reviewers actively replaying a short narrative game rather than simply finishing it once — is a meaningfully positive signal about how much genuine content sits beneath the surface of what looks, on paper, like a brief walking simulator.

What the achievement data adds

Global achievement data, spanning 34 tracked milestones, shows a broad, gently sloping curve rather than a single steep cliff: the most common achievement sits at 66.4%, and completion tapers steadily down through the list rather than falling off a specific edge. Notably, over a dozen achievements sit below 20%, and several — including ones tied to specific dialogue discoveries and side-content chains — sit below 10%. That spread is consistent with the review base's account of a game containing considerably more content, branching and hidden detail than its short main-path runtime suggests, and it also lines up with the critical review's account of side content that's genuinely easy to miss or permanently lock yourself out of without realising it.

A small but early, near-uniform sample

It's worth being direct about scale here: at 65 total reviews at the time of writing, this is a genuinely small sample for a Very Positive aggregate score, with only two negative English-language reviews surfacing in the entire dataset pulled for this piece. That near-uniform praise is a real and meaningful signal, particularly given how specific and consistent the reasons for it are across reviewers who don't appear to be echoing each other, but a small sample size means it should be read as a strong early indicator rather than a fully settled verdict — a wider audience discovering the game may yet surface complaints, particularly around the dialogue-puzzle friction the more detailed critical review already describes, that haven't had the numbers to show up in force so far.

Final verdict

how to kill a fly [ H2KAF ] takes a genuinely uncommon mechanical premise — surviving as a voiceless mimic in a corporate dystopia — and builds a short, densely written, visually distinctive game around it that has won over almost everyone who's played it so far. Its world-building, writing and plastic-green art direction are its clearest strengths, praised with unusual consistency across the review base, while its dialogue-choice puzzles are the one place where reviewer opinion genuinely splits, between players who found working out the right thing to repeat satisfying and at least one who found it borderline unplayable without the game's own assist mode. At NZ$15.75 for a tightly edited, repeat-playthrough- worthy few hours, this is an easy recommendation for cyberpunk and narrative-puzzle fans specifically, with the caveat that its central mechanic won't click painlessly for everyone.
