20 minutes+ staring at a computer screen is nothing to brag about! ;-)
Got past that one though and now it the puzzle hints "I want to kiss you." Can't get this one and I'm tired. Will try again tomorrow.
(I did run thru them again several times and I did notice that once it got to the last one I was stuck on I was able to see it rather quickly. I think doing that readjusts your eyes and may help. )
