Key & Compass presents:
Plane Walker
by Jack Comfort

Plane Walker is a Glulx interactive fiction game written with Inform 7 and is © 2021 by Jack Comfort. It was an entry in IF Comp 2021 where it took 68th place.

In this rather odd game, you play as someone who wakes up disorientated inside a deserted aeroplane in mid-flight. Where is everyone? Is the pilot gone too? Where is the plane headed? Why are you even there? All you know for sure is that you must get off this plane.

This solution is by David Welbourn, and is based on Release 1 of the game.

SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.

The Northern Aisle

> x imposing door. x keypad.

> hit keypad. (need a harder, resilient tool)

> hit keypad with pencil. (That did nothing. Hmph.)

If you examine the individual keys of the keypad (and why would you think of doing that?), you learn that the "6" key is the most damaged.

> x key. x 0. x 1. x 2. x 3. x 4.

Aeroplane Seat 34A

> unlock door with keys. s.


> x toilet. enter toilet. (cant: worlds clash)

CAUTION: If you take too long to successfully enter the toilet, you die.

Only glowing items (bag and maths) may come with you, and they must come with you. Drop the pencil, manual, keys, and ticket before entering the loo; they may not come with you.

Awkwardly, you can only drop things you're directly carrying. So you must take the pencil from the maths book and the ticket from the bag before you can drop them.

> drop manual, keys.

> take pencil, ticket.

> drop pencil, ticket.

> enter loo. (+7. You are now in...)

Lecture Hall

Note that the square root sign looks like a 'v'.

Game says to re-examine this door when you have something to write on.

Return to the head of the lecture hall:

> w. n. n. n. e. e.

Head of the Lecture Hall

> put maths on lectern.

There is no indication by the game that the east direction changed in any way by putting the maths textbook on the lectern. This is completely unclued:

Blank Note Card

Head of the Lecture Hall

You now notice an index card in the maths book.

> x card. take it. take pencil.

With the card out of the way, what do the rest of the maths book pages look like?

> e.

Page 23

Annoyingly, you can't refer to the "-" as a minus, hyphen, symbol, or sign.

> x -. (Room to left and right of it?)

> right. (Its negativity enters your soul.)

> turn page. (Soul shifts.)

Head of the Lecture Hall

Are you still negative? Yes, but only when in the maths book.

> e. turn page. g.

Page 10

I don't know how you're supposed to know about the "say hello to" command. CAUTION: Don't say hello to the ghostly being or you'll be multiplied by zero!

> say hello to small. (You were both negative; now you're both positive.)

> say hello to small. (+2. Feel something materialize out by your body.)

Hm. What if you enter the "V" when negative?

Although "open door" fails here, a simple "east" works to open the sealed door from this side.
