Endacopia Office Walkthrough — Mouth, Credibility and the Core

Direct Answer

The Office is the Chapter 1 hub where you recover the Mouth and work toward the Core. The route in short:

Button room → enter Help Me Talk → get the Mouth.
Earn Credibility (personality survey, phone jobs, dice games).
Gambling Den → beat the dice gamblers (Against All Odds achievement).
Chain the rewards — Flower → Wrench → Core Key — and head for the Core on the second floor.

Optional: the Office secret (Telescope + phone number 277-5944) is required for Ending C — see the passwords and codes guide.

The Office has a room of floor buttons that accept phrases. Without the Mouth you cannot talk to anyone here, so make this your first stop:

Enter the button room.
Spell out Help Me Talk with the buttons.
The computer restores Mellow's Mouth — now conversations, the survey, and the phone jobs all unlock.

The Office switch panels gate parts of the area. The reported working sequence is:

Yellow ON → Yellow OFF → Dark Blue → Light Blue → Purple → Red

Flip them in that order and the blocked route opens. If a later patch changes the order, the in-room clues take priority over any guide.

Office progression runs on a Credibility score. The reliable ways to build it:

Activity	Where	Notes
Personality survey	Office terminals	Answer the questions; clicking the achievement poster later unlocks the Achievement Unlocked achievement
Phone jobs (Jobs app)	Office computer	Six call gigs — advice lines, homework help, roleplay calls. Good Credibility per call
Dice games	Gambling Den	Highest payout; see below

Farming tip: the phone jobs are the steadiest Credibility source — better than replaying the gambling machines.

With enough Credibility you get reassessed and the Gambling Den opens.
Beat every dice gambler at the tables.
Winning the full set awards the Against All Odds achievement and starts the reward chain: Flower → Wrench → Core Key.
The Core Key opens the way to the Core on the second floor — the Office finale, where the Genesis AI encounter (fight or skip via the water short-circuit) waits.

One of the three area secrets for Ending C is here:

Bring the Telescope (reward from the Timesville party — password Yellow).
Use it to spot a figure displaying 277-5944.
Dial the number in the Jobs app, then follow the clue near the vending-machine stairs.

Step-by-step detail is in the passwords and codes guide.

Mouth: dialogue options appear everywhere in the Office.
Switch puzzle: the gated route opens.
Credibility: your score is displayed when you check; the reassessment prompt appears once you cross the threshold.
Gambling Den: Against All Odds pops after the final gambler falls.
Secret: the Ending C progress flag advances (check against the Ending C guide's three-secret list).
