Was just recently introduced to Twine, and started to look at it. I used to have students write Choose Your Own Adventure (CYOA) books using computer programming a LONG time ago, when it was necessary to work a lot harder to produce text that linked to other text successfully. This is SO much easier. I haven't investigated the advanced features that will supposedly allow you to add pictures, but I intend to when I get a bit of time.
Glenhaven's theme for this year is "Making Good Choices" and so, following that theme, I created a VERY short Choices example using Twine. It contains just two of the everyday opportunities students have to make choices.
You can find it here:
I encourage you to check out Twine. I like the possibilities.
Please let me know if you try it and consider sharing a link to your student's creations here.
