That is fun! Even if you did have some that are favorites, its even more special that we can't tell because you put so much love and characterization into them all!
I could see that since Ewan's & Lance's routes both felt almost like a different setting, and writing characters of a different species for Ewan's path (fairy) with their own rules and morals must have been a bit of a left turn. They ended up being some of my favorites because of that duality, though! It adds a bit of spice to your stories, because even though they're all intertwined they're each unique. That's something you don't see in visual novels much, and I love it!
