IN FALSUS TIPS

Rebind the default keys

The default 6K layout — LShift / A / S / D / F / Space — puts your pinky on LShift for entire charts, and it will cramp. Move the six Floor lanes to keys your hand already rests on (many players use S / D / F / J / K / L, or A / S / D / F / G / Space). What matters is that one finger hovers over exactly one lane.

Start on MIN, not on your pride

MIN (Minimal) is a 4K chart with static finger positions — four lanes, no shifting. It exists so you can learn how In Falsus feels before it tests you. Clear a few MIN charts before touching EVO, where the active lanes start shifting under your hand.

Learn the keyboard/mouse split early

Your keyboard hand owns the six Floor lanes; your mouse owns everything else. Field notes ask you to hold the cursor inside a moving region, Flick notes ask for a directional swipe. Trying to play pure keyboard stops working the moment a Field note appears — build the two-hand habit from day one.

Read the judgement text, not just the combo

Every note reports EXACT, EXACT LATE/EARLY, or NEAR LATE/EARLY. If you consistently see LATE, you are hitting behind the beat — adjust your timing, not your song choice. That LATE/EARLY bias is the single most useful diagnostic the game gives you.

Play the free demo before release

The Steam demo (currently v0.3.1) already ships six songs and a playable Card Integration and Iota system, ahead of the full release on 2026-09-09. Everything in this guide can be practiced there today.

Keep the Field cursor in small, constant motion

Field notes keep a region purple while your cursor is inside it and turn it red when you stray. Staying outside too long triggers a brief input dead state where your hits stop registering. Small continuous circles inside the region are far safer than parking the cursor on one edge.

Memorize the Flick colors before the chart asks

Flick notes are color-coded: yellow means flick left, green means flick right, and the swipe has to cover the note's full horizontal length. A short, lazy flick on a wide Flick is a BREAK. When yellow or green appears, your mouse hand should already be moving.

Time your Resonance burst for the back of the Phase

EXACT hits fill the Resonance gauge; a full gauge makes your hits crit for ×5 damage for the rest of the Phase, and the gauge resets every Phase. Since damage per note is fixed, the crit window matters most where the chart is densest — usually the back half. Hold your accuracy through the build-up so the gauge tops off right at the climax.

Holds are free accuracy

Hold notes have no release timing in In Falsus — hit the head on time and keep the key down until the tail ends. There is no penalty for holding too long, so treat every Hold as a free EXACT and a chance to reset your hand position.

Wide notes mean the mouse, always

Full-width notes only appear on FBD (Forbidden) difficulty and can only be cleared with mouse input. If you are moving from ULT to FBD, this is the real jump — not the note density. Get your Field control comfortable on lower difficulties first.

Fill colored Zones before anything else

A Blueprint's colored Zones are where base Power, Defense, and Trait Slots come from — blank tiles are safe but grant nothing. On any new Blueprint, cover every colored Zone with matching Iota first, then optimize. Check the layout in the solver before you commit pieces to it.

Two penalties already cost you half the card

Penalty scaling is brutal: 0 penalties = 100% stats, 1 = 89%, 2 = 56%, and 3 or more = 0%. Going from one penalty to two nearly halves your card. Overload, Out of Bounds, Overlap, Disconnect — and uncapped Falsehood — all count. Read the penalty line before you craft.

Respect the hard placement rules

Iota cannot be rotated or flipped, you can stack at most 3 pieces per tile, the Iota Limit caps how many you can place, and the finished card must keep both Power and Defense above 0. Place your biggest Tier pieces first — they are the ones that will not fit later.

Protect your average Potency

Card stats scale with the Potency Multiplier: average Potency ÷ 100. One low-Potency filler piece can drag a whole card's output down by more than an empty Zone would. If you must choose, leave the tile blank and keep the average high.

Build around your character's skills

Each character's Infusion skill gates which Iota tiers you can use per color, and their Core Skills add tolerances that soften placement rules. Nia's 'Path to Reality' leans Red, Mei's '4AM' leans Blue — matching your farmed Iota colors to your character saves you from a dead inventory.

Sequence your five cards by Phase

A loadout holds up to 5 Cards, one per Phase slot, and the chart is split into 5 Phases. No two Cards can come from the same Blueprint. Put your highest-Power card on the Phase where you are most accurate — damage per note is your Total Power divided by total notes, so accuracy is what converts stats into damage.

An empty slot is a 100/100 placeholder

Slots you do not fill default to a 100 Power / 100 Defense card. That is fine for early encounters — do not craft a weak card just to fill the fifth slot. Wait until you have Iota worth slotting.

Manage Resolve, not HP bars

Your Resolve gauge equals your Total Defense. You win — and Connect the encounter — by pushing the opponent's Resolve below 0 while yours stays above 0. Opponent BREAKs deal ×5 crits against you, so on hard charts, survival is an accuracy check too.

Exploit the color advantage cycle

Color advantage runs Red ⇒ Green ⇒ Purple ⇒ Yellow ⇒ Blue ⇒ Red, one-directional, and is worth ×1.25 damage. It will not save a bad run, but on borderline encounters it is the difference between Connect and retry. Check the encounter's color before locking your loadout — or simulate it first.

Higher difficulty is a damage multiplier

Encounter rewards scale with chart difficulty: Multiplier = 1.00 + Level × 0.05. Playing one difficulty step up with slightly worse accuracy often still out-scores a safe clear. Find your break-even point before you grind.
