Here's a text adventure/interactive project I've been working on with various people for HarperCollins, to promote "Annihilation" - a new book by Jeff VanderMeer, the first part of a trilogy which will be released this year. Have you got what it takes to join the Southern Reach?

Excellent. Was it all coded in Quest? Can you tell us how you did the map?

It wasn't coded in Quest, although there is a small amount of overlap - there's a C# version of Quest's text processor in there, for example.

The script itself is written using a modified version of the format I'm developing for a new project called Squiffy, which is a simple compiler for multiple choice interactive fiction - see https://github.com/textadventures/squiffy

The map is rendered using PaperJS - see http://paperjs.org/ - this is the same library that Quest uses for displaying its map, so the experience there was certainly useful.

After posting, I did wonder if the map was two images, the dot that stays still, and then the map, and the map was moved using a CSS transition.

I saw your posted something about Squiffy at intfiction. Sounds interesting (but a simple user interface like Twine would make it more generally attrractive).
