Heartworm

Introduction

Heartworm sends its protagonist through a PS1-inspired world of grief and the supernatural, armed with a camera that doubles as both weapon and investigative tool, in a game explicitly built as an homage to 1990s survival horror. Developed solo by Vincent Adinolfi and published by DreadXP, it released 31 July 2025 and holds a Very Positive rating that has stayed remarkably consistent — 86.0% across both its 493-review all-language corpus and its 413-review English-language sample. This review reads all 58 of the game's English negative reviews in full, and finds an unusually coherent, specific counter-argument running through nearly all of them — one distinct from vague disappointment, and worth reporting in the critics' own precise terms.

Presentation everyone agrees on

Before the criticism, it's worth being clear about what draws consensus. Visual presentation earns near-universal praise across this review's entire sample, positive and negative alike — detailed, evocative PS1-style environments that even the harshest critics credit as genuinely impressive. Music and overall atmosphere earn the same treatment, described consistently as the game's clearest, most reliable strength. One detailed positive review captures the homage precisely: "Take the camera combat mode from Fatal Frame series, Add the atmosphere of the Silent Hill series... Throw in some puzzles like the early Resident Evil games." Several reviewers describe a genuinely tense, promising opening stretch before the issues below begin to surface.

"What do you get when you remove the survival and the horror?"

Here's the thesis running through this review's full read of the negative sample, and it's specific rather than a matter of taste. Reviewers argue Heartworm reproduces the visual grammar of classic survival horror — fixed camera angles, locked doors, item-based puzzles — without the systems that made that grammar meaningful in the games it references: scarce resources forcing real risk assessment, combat with genuine stakes, tension built from vulnerability rather than atmosphere alone. "What do you get when you remove all of the survival and all of the horror from a survival horror game? You get Heartworm," reads one 44-vote review, calling it "a surface level love letter to games leagues better than it could ever hope to be." Another, more measured, makes the same structural point at length: "Heartworm tries to emulate the classic survival horror formula, but it does so without truly understanding what made those games compelling in the first place." A third compares it specifically to Resident Evil's inventory-and-ammo tension, arguing Heartworm never replicates the meaningful trade-offs that system created.

Combat draws its own specific criticism distinct from the broader thesis — 16 of the 58 negatives raise it directly, describing it as minimal or functionally absent for large stretches of the game. And difficulty is criticised from both sides of the review split, not just the negative one: one of the game's own positive reviews, 66 votes, opens by calling itself "barely a positive review," specifically because the easy difficulty undercuts the tension the atmosphere works so hard to build.

Story and writing draw a smaller but real critique

Beyond the mechanical argument, a meaningful share of this review's sample raises story and character writing as weak points. Dialogue and voice acting are singled out in several reviews as falling short of the presentation's polish, and one reviewer specifically criticises an overwrought teenage-angst tone in the central character that undercuts the story's handling of grief, the theme the game is explicitly built around.

A transparency note on the top review

Worth flagging plainly: the single highest-voted positive review in this game's entire corpus, 170 votes, opens with self-disclosure that its author worked on Heartworm as a co-writer, contributed early concept art, and voiced a character. That's not a reason to discount the review — the author is upfront about it rather than concealing it — but it's relevant context for readers weighing how representative that particular endorsement is of the wider audience's experience, distinct from the independent enthusiasm found elsewhere in the positive sample.

What the numbers suggest

Steam's achievement data is consistent with the "too easy" complaint several reviewers raise: across 19 achievements, the median completion rate is 22.2%, with the easiest at 90.7% — a comparatively generous completion curve for a horror game, suggesting most players who start Heartworm see a significant amount of it without the difficulty wall genre peers often present.

Final Verdict

Heartworm succeeds unambiguously at what it visually and sonically sets out to do — this review's full read of its negative sample finds essentially no dissent on atmosphere, presentation or the strength of its opening hours. Where a genuine, specific and consistent critique emerges is mechanical: reviewers across dozens of independent negative reviews make essentially the same structural argument, that the game reproduces survival horror's surface language without the resource tension, combat stakes or difficulty that made the genre's classics function as more than atmospheric homage. That's a real, well-documented limitation rather than a matter of individual taste, and it's worth knowing clearly before buying: come for a beautiful, easy, atmospheric walk through PS1-horror iconography, not for the tense survival experience its influences promise.
