I've been working with Twine 2.0 for a few weeks now, and have been very content with the software's capabilities thus far, and I'm incredibly grateful to the developers for open sourcing it. Now, with that being said, I do have a question.
The default method of linking passages isn't what I intend to use. I much rather utilize the type multiple choice depicted below. As I understand JavaScript could provide me with an alternative for choice selection, but I've been unable to find any details for such code; as far as Snowman 1.1 goes.

Could someone please explain how to script Multiple Choice boxes instead of the standard passage linking? I'm using Snowman 1.1, JavaScript, and HTML to create this particular CYOA game.

I'd do a mock-up, but really, this shouldn't be all that hard to visualize. Basically, imagine it similar to what you have now, save without the next button.
Attached is a Twine 2 archive ready for import.
Oh well, no matter. I'll simply attach it to this post. The only things you really need to look at are the starting passage, to see what I did with the links, and the Story Stylesheet, for the styles.
