Twine is a wonderful editor that lets you create interactive fiction. It auto-builds a big flow chart, and has some programming paradigms that allow adding many involved paradigms that wouldn’t be possible in a Choose Your Own Adventure book, for example.
I recently took my text adventure Recurring Nightmare and rewrote it slightly as Dream Sequence, which I’m going to run as an “in person” text adventure over the computer for my company. When I did that, I decided it would also be fun to try and write it up with Twine, since it’s a fairly simple map and game.
I had to do some strange work to learn how combination locks work, but with the help of the internet I managed to get it in. The best part of Twine is that it exports as a single HTML file, making it pretty easy to post it in various places. So, you can now play through it on your own below. Enjoy.
