Arcaea vs In Falsus

lowiro made Arcaea first: a mobile (and later Switch) lane game with sky notes and twisting arcs. In Falsus is the studio’s second original title, built for PC Steam, with a mouse-driven aerial Field and a long Japanese-voiced Scenario. Players who treat the new game as “Arcaea with extra keys” bounce off the demo. This page is the translation layer.

If you have not installed the preview, start at getting started. If your hands already hurt, open controls.

Platform and product

	Arcaea	In Falsus
Platforms	iOS, Android, Nintendo Switch	Windows via Steam
Input	Touch (or Switch controls)	Keyboard Floor + mouse Field
Structure	Music-first, story logs as unlocks	Scenario-first, Encounters as scenes
Voice	Limited / partner lines	Full Japanese voice acting at launch
Economy	Fragments, memories, partners	Iota, Blueprints, up to five Cards
Multiplayer	Not a shared-session title in the usual sense	Single-player only

Steam lists In Falsus as Playable on Deck, not Native. Arcaea’s phone muscle memory does not include a mouse flick.

Notes that look related and are not

Arcaea sky notes and arcs live above four floor lanes. In Falsus Floor lanes go up to six keys (default Left Shift, A, S, D, F, Space) and the Field is a second judgement line driven by cursor motion, including yellow-left and green-right flicks. MINIMAL charts drop you to four keys on purpose. That is why veterans still belong on MIN once: the new limb is the mouse, not another trill.

Judgement vocabulary does not carry. Arcaea PURE/FAR talk will not label an EXACT popup. Score in In Falsus is accuracy-first on the big number, with a separate Encounter Score and stars when cards are in play. Read scoring before you screenshot a combo and call it a partner skill.

Story shape

Arcaea’s world is abstract: Hikari, Tairitsu, glass memories. In Falsus is a near-future high school under a Shroud, with Binds that display emotion and deceit, and five selectable perspectives (Nia, Mei, Ayame, Iris, Story Étienne). You do not level a partner; you pick a route. The character hub and Scenario guide are the right next tabs.

Cards are not Arcaea partners. Integrating Iota into a Blueprint is a hex puzzle with Overload and Out of Bounds penalties. Equip up to five Cards. They ride Encounters; they do not skip notes. See card integration.

The Cryogenic bridge

Camellia ft. Petra Gurin’s Cryogenic is an In Falsus original that also appeared in Arcaea Version 6.13 World Mode for a limited window, then Memory Archive. That is a song collab, not a chart port. Playing Cryogenic in Arcaea does not teach Field flicks. Playing it on In Falsus MIN 2 does. The official Camellia audio lives on the known song list.

MIRINAE (TAK × Zekk) is listed in community tables as an Arcaea original appearing on later In Falsus wheels. Same warning: new engine, new numbers.

What to unlearn in the first hour

1. Do not open ULT because you play FTR 10 in Arcaea.
2. Do not skip Scenario text to “get to the pack.” The song is the scene.
3. Do not hunt fragments or map tickets. Wishlist Steam and play the demo.
4. Do not expect a mobile port announcement in this wiki. None has been posted.

If the comparison still feels like a skill issue, it is probably binds. Stay on the keybind planner until MIN EXACTs return, then climb with difficulties. Same studio, different game. That is the whole point of a second title.
