In Falsus Is lowiro's Bet That a Rhythm Game Can Carry a Story

At its core, In Falsus runs on a signature control scheme built around six keys and the mouse. Notes stream toward you while a sweeping aerial Field asks the mouse to carry motions the keys cannot, and the two hands have to learn to cooperate. There are four difficulty tiers, and the jump from comfortable to genuinely testing is steep, which is exactly what a dedicated rhythm crowd tends to want. The charting is the headline attraction, and it feels authored by people who chart for a living rather than generated to fill a track list.

That pedigree shows in the feel. Inputs read cleanly, the timing window is honest, and the harder charts are built to be practiced and beaten rather than simply survived. If you came from Arcaea expecting lowiro's precision to translate, it does. The novelty here is the mouse, which turns the aerial Field into a second instrument. It takes real time to click, and the first hour can feel like patting your head while rubbing your stomach, but once it lands it gives the game a texture most keyboard rhythm titles do not have.

Around the notes sits a surprisingly deep card system. You collect materials, craft unique Cards that grant gameplay advantages, and arrange those materials inside Blueprints, grids that reward smart placement with stat boosts and bonuses. You can equip up to five Cards at once, so the loadout becomes its own small puzzle: every Card is different, every Blueprint is a layout problem, and optimizing them gives the between-song downtime an actual reason to exist. It is a genuine progression layer rather than a cosmetic bolt-on.

The narrative is delivered as a fully voiced Japanese ADV scenario, the visual-novel format lowiro clearly wanted to lean into. Five protagonists, each with their own perspective, are recruited into the government program at the story's center, and their threads gradually knot together. It is more substantial than the throwaway framing most rhythm games settle for, and if you are the kind of player who reads every line, there is a real arc to follow. If you are not, the game lets the music carry you and the story recede.

For content, the package is generous. There are over 70 songs, more than 40 of them originals, drawn from artists at the front of Japan's independent music scene alongside international composers, and the styles range widely enough that no two sessions feel identical. It is single-player only, with 25 achievements to chase, and the long tail comes from climbing difficulty tiers and refining Card builds rather than from any competitive mode.

The friction is honest to name. This is a premium-priced, single-player rhythm game aimed squarely at people who already love the genre, and the difficulty can spike sharply between tiers in a way newcomers may find discouraging. There is no co-op or competitive hook to fall back on, so the entire value proposition rests on the charts, the songs, and the story being enough. For the target audience they are. For everyone else, 39.99 euros is a lot to ask of a maybe.

Visually, In Falsus is unmistakably a lowiro game: clean, anime-styled, and confident about negative space. The playfield keeps its focus tight, the aerial Field sweeps in as an elegant second layer rather than clutter, and the interface stays legible even as the charts get busy. It is a look built to disappear into flow, which is the right instinct for a rhythm game, and the visual-novel sequences give the cast enough presence to make the story feel like a place rather than a menu.

The soundtrack is the real work of craft here, and it is where the money shows. More than 70 tracks, over 40 of them written for the game, pull from Japan's independent scene and a spread of international artists, and the range is the point: this is not one producer's signature sound stretched thin but a curated set that keeps surprising you. The best charts are the ones built to serve their song, and In Falsus has enough of those to justify calling itself a music game first.

The full Japanese voice acting ties the presentation together. It lends the ADV scenes weight they would lack as silent text, and it signals how seriously lowiro takes the fiction. The whole production reads as deliberate, from the restraint of the UI to the breadth of the music, and that coherence is a large part of why the game feels worth its asking price to the people it is aimed at.
