Now fire in the eye looks like wired or sick mudokons icons to me:
Also, Ed really reacts to
FIRE with
CLOSER, it isn't a generic response.
Actually he reacts to every input with
FIRE in it:
"1123411
FIRE1112351",
"
FIRESTARTER",
"WATER EARTH
FIRE WIND"
all will give "
CLOSER" respond among generic ones.
So perhaps Ed waits for word with -FIRE- in it?
