Which version of Twine are you going to be using? Which would you recommend? I am mostly familiar with Twine 1, so I'm not sure which I will be using yet myself.
I'm planning to use Twine 2 as it seems more easily accessble on multple devices. Consider the possibiloty on working on a game via a smart phone. I recomend watcthing VegetarianZombie's tutorials before the jam as they are pretty indepth--
I'm using Twine 2. Snowman in that version is WAY more friendly for me, and doesn't have the time-consuming whitespace cleanup you have to do on the other formats.
