At the risk of being all "I just started and I'm stuck"...
What I seem to have open right now are three red dead ends and a blue dead end, and half of "Green Letters". (But the hints on "Green Letters" only apply to the half of it I've solved.) What am I missing that would help me progress?
EDIT: never mind; I had the right answer, but was typing it in the wrong format. (Which feels a little guessing-game-like, not to accept the right answer in a different format, but.)
