Glad to hear you had a good time with it, your words honor me^^
That actually is a pretty nice idea. Shouldn't be that hard to add and could also gives hints to find them. Will add that to my to do list and add it with the next patch.
Also the hardest ones to find are properly: Fox (Related to red gates in the forest), Chicken (Related to a Chicken Guild Quest after finishing Sheep Story) and Satyr (Related to Broken Coin Quest). Also no bad end is missable, so no worries about that!
