In Falsus

Introduction

In Falsus, released 9 September 2026 by lowiro, the developer behind the mobile rhythm game Arcaea, is a PC rhythm game built around a distinctive one-handed control scheme and a fully-voiced visual novel following five interconnected protagonists in a near-future world of government surveillance and hidden truths. It sits Very Positive with a substantial and unusually engaged sample of 353 reviews, and reading widely through this sample reveals genuine, specific and repeated enthusiasm for both halves of the game's hybrid design, sitting alongside a smaller but consistent set of structural and pricing complaints this review treats as genuinely significant.

An unusual control scheme reviewers take seriously

The clearest, most consistent praise across this sample concerns the core rhythm mechanics themselves. Reviewers repeatedly describe In Falsus as genuinely, deliberately difficult in a way that rewards real mastery, with several self-identified veterans of other arcade rhythm systems, including IIDX and Sound Voltex, comparing its difficulty ceiling favourably to those established benchmarks. At least one detailed, long-time Arcaea player specifically praises the one-handed input layout for making them feel like "a rhythm game beginner all over again," framing that renewed challenge as genuinely refreshing rather than frustrating, while flagging specific accessibility concerns around side-lane note visibility discussed further below. Multiple reviewers also specifically note flexible hand assignment, describing playing six-key patterns with their non-dominant hand by choice, a level of input customisation this review found repeatedly credited as a meaningful design strength.

Song selection, audio engineering and presentation

Beyond the core mechanics, this review found strong, specific and repeated praise for the game's musical foundation. Reviewers consistently credit the roughly seventy-song library with strong variety, and at least one detailed reviewer specifically notes In Falsus as the first rhythm game they've encountered to support ASIO low-latency audio, a technical detail several reviewers frame as evidence of serious genre-specific engineering care rather than a generic port of mobile design choices. Presentation draws similarly strong praise, with reviewers repeatedly comparing the visual novel's structure and visual polish to Cytus 2, another well-regarded rhythm-narrative hybrid, and multiple reviewers specifically praise full voice acting for major characters across the story segments.

A visual novel that wins over reluctant players

A specific, recurring pattern across this sample deserves direct attention: reviewers who explicitly state they came for the rhythm gameplay and expected to skip or tolerate the story describe getting genuinely pulled in regardless. Multiple reviewers separately frame this as surprising given their stated general dislike of visual novels as a format, with one describing themselves as "not a fan of visual novels" before admitting the story "got me hooked" despite trying to skip it in the demo. That kind of reluctant, converted praise reads as a stronger signal of genuine narrative quality than enthusiasm from players who sought out a visual novel experience from the start.

Song unlocks gated behind mandatory story progress

Set against that praise, this review found the single most consistent and substantive structural complaint across this sample: the majority of the song library is locked behind visual novel story progression, and reviewers primarily interested in rhythm gameplay report this as a genuine barrier rather than a minor inconvenience. At least one detailed negative reviewer reports having only 9 of 70 songs unlocked after a meaningful time investment, ultimately deciding the required story-mode pacing wasn't worth continuing toward the full asking price. This review reads this specific structural choice as the fulcrum most of this sample's disagreement pivots around: reviewers who embrace or grow to enjoy the visual novel report a rich, well-integrated hybrid experience, while reviewers who came purely for rhythm gameplay report the same structure as an unwelcome gate between them and the content they actually paid for.

A removed demo, and a steep price to gamble on

Compounding that structural complaint, this review found specific, repeated criticism of the removal of a previously available free demo. Multiple reviewers note the demo had let undecided players confirm the game's unusual one-handed control scheme genuinely suited them before committing to a purchase exceeding fifty New Zealand dollars, an option no longer available at the time of this review's research. Given how consistently this sample describes the control scheme as unusual and initially disorienting even for experienced rhythm game players, this review reads the demo's absence as a meaningful, specific gap between what reviewers describe needing to make an informed purchase decision and what's currently available to prospective buyers.

Readability complaints on the side lanes

A separate, specific and repeated technical complaint concerns note visibility. Multiple reviewers independently request improved readability for notes on the game's side lanes, describing them as difficult to distinguish against moving backgrounds, with specific requests for adjustable background dimming and customisable note colouring or thickness. This review found this complaint repeated closely enough, across reviewers with meaningfully different total playtimes, to treat it as a real, currently unaddressed usability gap rather than an issue limited to inexperienced players still learning the control scheme.

A vocal minority, sharply critical

It's worth directly reporting the sample's more sharply negative voices rather than only its constructive critics. A small number of reviewers within this sample specifically criticise the writing quality of the visual novel segments in pointed terms, and separately criticise the pricing model as exploiting the format to gate content behind lengthy, unskippable text. This review found these criticisms sit clearly in the minority relative to the sample's overall Very Positive standing, but includes them directly for balance, since they raise specific, articulable concerns about writing quality and monetisation structure distinct from the readability and demo-availability complaints raised elsewhere.

Why this review weighs the structural complaint heavily despite the strong overall score

It's worth being direct about how this review balances an overwhelmingly positive reception against a structural complaint serious enough to hold the value score down meaningfully. The distinction that matters is that the gated-unlock structure isn't a matter of individual taste the way difficulty or art style might be, it's a specific design decision that determines what a majority of paying customers can access and when. A game can deliver genuinely excellent content in both of its component halves, as this sample strongly suggests In Falsus does, while still making a specific structural choice that meaningfully limits how quickly and how flexibly players can reach the content they specifically paid for. This review's score reflects both of those realities simultaneously rather than letting the strong overall reception override a real, specific and widely-reported structural friction point.

Final Verdict

In Falsus delivers a genuinely inventive, difficult rhythm game paired with a substantial, well- produced visual novel that this large sample repeatedly credits with winning over even reluctant, rhythm-focused players. What holds this score back from matching the sample's overwhelmingly positive tone is a specific, repeated structural complaint about song unlocks gated behind mandatory story progression, compounded by the removed free demo and real note-readability concerns on the side lanes. Worth it for genre enthusiasts and existing Arcaea fans prepared for its steep price and unusual demands; players wanting a straightforward rhythm game with no visual novel obligations should wait for a sale or a possible demo return.
