Should have been — ULT 10
ARC 3: HEAVEN'S CHAINS · FRUMS · VERIFIED FRAME BY FRAME
Should have been is Frums' contribution to Arc 3: Heaven's Chains, cataloged at ULT 10 with an FBD 13 top tier — and the game keeps the title all lowercase. This page walks the chart through a verified single-take ULT 10 sightread that ends DIVE CLEARED at rank A. The FBD 13 capture isn't verified yet, so every figure below describes the ULTIMATE 10 chart — the levels table still lists its FBD ceiling from the song database.
TL;DR
- ▸Should have been is a Frums track in Arc 3: Heaven's Chains (v1.0.2c): MIN 3, EVO 6, ULT 10, FBD 13 — and the in-game title stays all lowercase.
- ▸The ULT 10 chart opens with taps and a cyan hold, stacks a stepped purple beam, doubles into twin beams and crossings, then goes full width before an S-curved finale over yellow holds.
- ▸The source sightread ends DIVE CLEARED at rank A — 093'660'933, MAX LINK 380, EXACT 1407 against 59 BREAK — with the uploader's Assist Mode shown enabled on screen.
- ▸Every figure deep-links TrappyTheDemon's upload at the shown moment; the FBD 13 level comes from the site's song database and has no verified capture on this page.
SOURCE FOOTAGE
Every frame on this page comes from TrappyTheDemon's Should have been ULT 10 sightread (3:20): a full-screen playfield capture with no handcam, no facecam and no commentary — the upload has no auto-captions at all, so nothing here is quoted from speech. The recording follows one continuous take: song widget, dive, DIVE CLEARED, dive result.
Scope notes, stated plainly: the uploader's own screens show Assist Mode enabled, so this is an assisted sightread rather than a hardcore benchmark run. The source video is VFR, so deep-link seconds can land a second or two off the exact frame — the stills on this page were verified one by one. The upload closes on a Song Unlocked screen after the result.

HOW THE ULT 10 CHART UNFOLDS
8 FRAMES · TRAPPYTHEDEMON PLAYTHROUGHEight frames, one lesson each: what the song widget locks in, how the opening stacks, where the beams cross and double up, when the chart goes full width, and what a cleared-but-not-perfect dive leaves on the result screen. Timestamps quote the source video at the shown moment.

Read the widget: Should have been, ULT 10
The dive opens with the facts on screen: the song widget in the top corner names should have been by Frums and reads ULT 10 at SPEED 7.00, while the first taps and a cyan hold are already reaching the line. The A S D F lanes carry the chart from its first second — no warm-up.

The opening stacks a stepped purple beam
The opening's signature shape: a wide purple beam descends in visible steps, stacking across the lane group before it lands on the line in a burst of EXACT judgements. Read the width first — the steps tell you when, the edges tell you where.

Purple and pink beams cross at the line
The mid-chart's first trap: a thick purple beam leans in from the left lanes while a pink beam sweeps in from the right, and the two cross right at the judgement line. Commit one hand to the crossing point and let the other side pass — chasing both is how the combo dies.

Twin purple beams run in formation
A minute in, the chart doubles down: two parallel purple beams run side by side down the left-center lanes, close enough to cover each other's edges. The hands split, hold the formation, and ride it to the line together.

The whole highway goes purple
The chart's widest moment: a translucent purple panel stretches across the entire highway, its base dragging a white spark stream along the line while the lanes underneath stay busy. Width is the read — the panel eats your view, not your fingers.

An S-curved beam rides over yellow holds
Late in the chart the shapes stop being straight: a white-purple beam snakes down in an S-curve while yellow hexagonal hold outlines ring the lanes below. Keep the holds pressed and let the curve travel — the two hands work on different clocks.

A purple-and-pink pair closes the chart
The final seconds pair a purple beam with a pink beam descending in parallel onto the line — the last distinct shape before the chart runs out of road. It lands, the highway empties, and the dive is already decided.

Read the result: cleared, not perfect
The DIVE RESULT screen is the honest ending: rank A, score 093'660'933, DIVE CLEARED — with EXACT 1407, a second EXACT band at 160, NEAR 101 and BREAK 59 behind a MAX LINK of 380 and a MISS GAUGE at 15. The ASSIST MODE row sits below, shown enabled. A clear here did not demand perfection — it demanded recovery.

SHOULD HAVE BEEN FAQ
SEARCH INTENT · ANSWEREDHow hard is Should have been in In Falsus?
Per the site's song database (v1.0.2c): MIN 3, EVO 6, ULT 10, FBD 13. The in-game ladder maps those tiers to 4-key, 5-key, 6-key and 8-key layouts, and the playfield widget on this page reads ULT 10 on the chart being played. FBD 13 is the game's top documented tier.
Is this a guide to the FBD 13 chart?
No — and the page says so. The verified footage here is a single continuous ULTIMATE 10 sightread. Should have been's FBD 13 chart is documented in the song database but has no verified capture on this page, so nothing above describes the FBD pattern itself.
Is the run a full combo?
Cleared, not perfected: rank A with EXACT 1407, a second EXACT band at 160, NEAR 101 and BREAK 59 — MAX LINK 380, MISS GAUGE 15, final score 093'660'933. The uploader's own screens also show Assist Mode enabled, so treat it as an assisted sightread, not a hardcore benchmark.
Who made Should have been, and which arc is it in?
Should have been is a Frums track in Arc 3: Heaven's Chains, documented at game version 1.0.2c — and the in-game title stays all lowercase. The chapter's track group and unlock path are covered in the site's Arc 3 guide.
What keys does the ULT chart use, and at what speed?
Six inputs: the A S D F lane keys plus Shift and Space — the capture's German UI labels them Umschalt and Leer on the side ramps. The song widget shows the chart running at SPEED 7.00, the note scroll speed this recording used.
