I can't tell if they are blue or blue green, or green and went with green. I've got weird eyes, not to belabor all that, please no, too much from me already on a2k, but my take was somewhere in the general range.
Actually, now that you mention it, I'd like the Url stuff in louder color and, when I did do my own back when, made them darker..
I've got creds re difficulty, but understand the rest of the world has other stuff going on.
Also, those itty bitty clues are too small. Not by a lot, but somewhat. People seem not to get it.
