I'm voting for Alicey too, but for purely visual reasons. She looks different than the other characters who are rather plain and undistinguished from masses of manga characters out there. She is the only one I could identify if all your characters were lined up next to a dozen other similar characters from other strips. They are sort of generalized but Alicey has her own look.
I really liked her look back in the beginning when you were using markers. The coloring on her gave her a depth that other characters didn't have visually. And of course the freckles!

Of course I'm a big fan of cast pages to help me remember who everyone is too. After reading the archive I will usually wait a few weeks for a strip to build up a few more episodes before reading it again so I can take in more of the story at once. It is easy to forget who is who just on visual clues unless they are distinguished somehow.
Now having given that critique, let me say that it wouldn't stop me from reading your strip and a lot of my favorite strips I have the same issue with. One of my favorite strips, Questionable Content, drives me nuts sometimes because of that.
