Along with Chad Coup, a fellow Course Director in the creative writing program, I gave a talk at Full Sail University about making games with Twine as part of the Full Sail On Air presentation series.
I covered the original version of Twine (v. 1.4.2), and Chad provided information about Twine 2.
The core resource I used in this talk has been extremely useful as an instructional tool for helping students who use Twine in my game writing class.
