"a ring that turns a huntsman into a princess," My favorite one of the many possibilites. At some point, I thought you were procedural generating the ring choices.
The Old Woman in the Wood
I wanted to do the jam since I also made a fairytale-based game for Ludum Dare 35, and that was really fun. This time I found myself looking at the story The Old Woman in the Wood. Something about the table piled with rings caught my imagination, and used that as a jumping-off point to play with some other fairytales as well.
As an experiment, I included a link to the source text of each fairytale on the bookmark/sidebar - I'm very curious to hear if people use it and find it interesting when reading my version of the stories, or if it's distracting.
