rajasekharan, can you give those of us who haven't gotten past level 16 some hints on how we could obtain the answer, or what exactly we are looking for? I have seen there is something written on the image if you adjust the contrast and brightness, or reduce it to greyscale to be able to see it better, but other than that, I am clueless as to how to use that information or if it is related at all. Any hints other than the ones already given would be helpful, but as for right now, I am clueless haha.
Edit: Okay, got the "Go in" part, but I don't understand what to do after you "Go in"
I see the space to clear, but I do not see anything to find for an answer..
