UPDATE: I’ve managed to slightly improve the terrible fuzzy quality of this Camtasia video. Apologies for the previous version.
In the first pass through creating a prototype in Twine we created screens for all the ‘good’ decisions, showing the best path through the scenario.
In the second video we begin to add the alternative routes. This might seem like quite a casual, ‘thinking out loud’ process. That’s because in real life it would be. This would be you in the creative phase, building up the script. You could, of course, have scripted it in Word and even had it signed off before you get to this stage. But I’d argue doing it this way – alongside your Subject Matter Expert if they’re game for it – brings you much closer to your finished product because you get a feel for the story and scenario as you are going. And, perhaps even more important, you get a Minimum Viable Product at the end – something you can try out with real learners and get better feedback than you could with a dry script.
