Bronze is a great starting place for those getting into IF. It has a generous hint system and puzzles that are just the right difficulty (for me, anyway!). Though it has some parallels to Beauty and the Beast, it is it's own story and not romantic, if that's a concern. I would recommend printing a map or drawing a map to keep track of all of the locations. I didn't visit all of the possible rooms (the ones unlabeled on the PDF map), so I assume there is an alternate, perhaps more favorable, path. Next, I plan on having my middle school students work through this story as an intro to IF!
