Wonderful game! Very elegant rules, and delightful illustrations too!
I recommend playing with a notepad open in background so that you can note down your word chains - this can prove very handy when a new word reveals to be close enough to a one that you have already visited.
The game also allows for some plural words (e.g. cats), declensions (e.g. paly), and uncommon words (nori? wold?? yird???), so don’t be afraid to try things out.
It would appear that I have distracted a few other people by linking them this game.
