Fun little demo. It did take me a while to figure out that I could move the windows up, which you needed to do to find the letter N. But luckily the hints were nice, so I did know where to look. It was purely by accident that I discovered it. I also feel quite rude for exposing the person who just took a shower, because of course I had to open every window before finally finding the window that contained the letter N. Just my luck haha.
