Bro I forgot I changed my fantasy world name lumfao

Anyways, my question still kinda applies, because I've been wondering if the title "Under The Mirror Moon" is still kinda not too long by any chance?

When I add a game name to it like "Under The Mirror Moon: Sadness" (game I'm currently planning btw :) ) do you think it's a good length for a title?

I suppose there are titles like "My Little Pony: Friendship is Magic", so this title isn't that long, but what if I wanted to add a title to it that's longer than one word? Just wanted to know some opinions on the title from other people, I like the title but I've been wondering if it looks good to other people.
