Key & Compass presents:
The Impossible Bottle
by Linus Åkesson

The Impossible Bottle is a Z-machine interactive fiction game written with Dialog and is © 2020 by Linus Åkesson. It was an entry in IF Comp 2020 where it tied for 1st place.

In this amusing but very puzzling game, you play as 6-year-old Emma Small. Dad's making dinner and wants you to pick up your toys and find some things for the table before the Taylors arrive. But when you go to fetch the tablecloth, you instead find a handkerchief. What's going on?

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.

I leave the exercise of figuring out the pecking order of the signature furniture items for another day. It's entirely possible that the size of a signature matters too, after all.

You've just walked through the open side of your dollhouse onto the table it's on. If you put the fire truck beside the table in your room and extended the ladder there, there's now the top of a ladder here at the south edge of the surface.

If you still haven't given the cufflink to Dad, go find him and do that and return here. After you've given the cufflink, Dad will put the cooked casserole on the table and wait here for you to place all the remaining table settings he asked for.

Also, once you've proven you know how to use the truck and its ladder to get around in the enlarged rooms, you don't have to explicitly refer to the truck and ladder any more.

Inventory

In this listing, I will group all versions of an item together, whether portable or not. The versions listed in boldface are portable; the versions listed in italics are not portable.

Refer to the Size-changing methods section on how to change the size of an object.

Dolls and creatures
Electronics
Furniture

Note that when the stegosaurus is stomping about in your room, he might easily knock any or all of the furniture out of the dollhouse. After you've dealt with him, you should put all the miniature furniture back where it belongs.

Gewgaws
Plants

Note that you may not take any of the plants from the window sills: the yellow primrose in the master bedroom, the reddish purple geranium in the study, the crimson red begonia in the landing, the white petunia in the sitting room, and the fern in the kitchen. None of these window plants are represented in the dollhouse either.

Other cloth goods
Other metal goods
Other paper goods

Progress

The response to SCORE or PROGRESS is:

Your current progress is percentage.

As best as I can determine*, progress percentages are awarded as follows:

* Unfortunately, there is no NOTIFY ON command to inform you when exactly you earn progress, but there is an ASCII art progress bar at the right end of the status line that gives a rough idea of your progress. (I note that the Dialog library does contain a NOTIFY ON command, but either it's new to the library or it was disabled for this game for some reason.)


Size-changing methods

To make something smaller:

Note that you can't take objects that are too big or too small, but you might still be able to interact with the object in some other way.
