Undo Tomorrow

Your Monday fell apart one e-mail at a time.
Then an older version of you stepped out of a hole in the air, handed you a watch, and left.

An ordinary inbox.
For about four minutes.

Northstar Systems, 14th floor. Coffee, the weekly numbers, a lunch you'll probably bail on. Then the mail starts arriving — and each one only after you've read the last.

Open the messages. Read them. When you've seen enough, do what your future self would do.

  1. Read your mail. All of it.
  2. Undo it. The button, or Ctrl+Z.
  3. Look again. Something else changed.

TEMPORAL ANOMALY DETECTED

An external record was modified before your recorded arrival.

Origin: UNKNOWN

“Remember. Just because you fix something… doesn't mean everything else stays the same.”

— You, from later

The rules

“You're not going to believe this,
but I'm you.”

  1. 01

    Only certain moments

    “It doesn't let you go anywhere you want. There are specific moments in the past that you can return to. Moments where something went wrong.”

  2. 02

    Back, then home

    “The watch can only take you to the past, and bring you back to your present. Don't ask me why. There isn't time.”

  3. 03

    Keep what you find

    “Some things you find in the past are going to be useful somewhere else. Keep them. Pay attention to everything.”

  4. 04

    Nothing stays put

    “Just because you fix something… doesn't mean everything else stays the same.”

Past destinations

Six recorded moments.
Each one went wrong on purpose.

The watch only resolves a moment when you know enough to need it. Here's what it's holding.

The Payment

  • Westview Apartments
  • Mon Oct 12 · 3:45 PM
  • Sun Oct 11 · 10:15 AM

The lobby kiosk says your rent was processed. The ledger says unpaid. A day earlier, in the middle of a maintenance shutdown, someone added a rule by hand — and sent one resident's rent somewhere it should never have gone.

Fuses, breakers, a receipt printer with no paper, and a user ID that isn't the contractor's.

The Broken Camera

  • Northstar · 14th floor
  • Mon Oct 19 · 6:20 PM
  • Tue Oct 20 · 9:10 AM

Your future self calls it a broken security camera. It works perfectly. It was told not to: recording off, head turned to a printer, its channel fed colour bars — on a work order approved with your ID.

Also featuring: the worst joke in history.

The Financial Error

  • Employee Financial Services
  • Oct 21
  • Oct 24
  • Oct 27

The bank says the missing $18,000 was authorised. Three days in Northstar's finance department show how: an authorization that asked whether you exist — not whether you agreed.

Correct the rule, and the proof of the crime vanishes with the crime.

The Data Leak

  • Restricted wing 14-R
  • Mon Oct 26
  • Tue Oct 27 · 10:15 PM
  • Thu Oct 29

The camera you repaired has recorded you walking into a restricted wing on the night of the leak. You don't remember it. The tape does. And eleven minutes later, there's a second entry the archive threw away.

Last Tuesday, 9:38 PM. You keep coming back to it.

The Warning

  • Tue Oct 20 · 7:10 PM
  • Sun Oct 25

Alex has a photograph: somebody who looks exactly like you, standing in a doorway behind her, on a night you swear you were home. Three evenings. A letter that never arrived. A door that was supposed to work.

The Missing Moment

  • Sub-level ██
  • Oct 16
  • Oct 20
  • Oct 27
  • ARRIVAL ADJUSTED

You asked the watch for October 4th, 11:42 PM. It said no, and put you somewhere else: a level under Northstar that has been sealed since the lockdown. Somebody has been living down there.

The finale. Everything you changed is down here at once. Four endings.

Same place. Different day.

Drag the hand.
Change the date.

Every place in the game exists on more than one day. Lights, stock, rain, the coffee machine nobody fixed since March — the world is rebuilt from what happened, and from what you changed.

The Future Self

Also you · years older, significantly worse off

Hoarse, hurried, and suspiciously well-informed. Shows up through holes in the air with good news, bad news, coffee and puns. Knows exactly which records you shouldn't read.

You told her you were working late on Tuesday. She believed you. She always believes you. Then she found the photograph — and she remembers every version of what you change.

The theme

Undo Tomorrow
(Dance Tonight)

The game's own song. Press play, and the watch keeps time with it — 117.45 beats per minute, measured.

Stay after the credits. That's all we're saying.

Go back. Find out what went wrong. Change one thing.
Come home to a present that remembers.
