I haven’t, but I’m adding it to the list. Thanks!

It was a bit labor intensive, but mostly because I wanted pictures. I wound up loading them to photobucket and using the tag.

Have either of y’all played with Oppia? It allows you to send a response based on any kind of input. I thought it had a lot of potential, but took way too long for me to build. I’ve been wanting to do something like this though, so I’m excited to try out Twine, thanks for sharing Evan!

That’s definitely a concern. Its easy to handle for compare tasks, but challenging otherwise. Some JS might make it possible to show/hide links based on an entered numerical value. Combining a back end to collect data would also make this really powerful.
