    I recognize that I am not very skilled at solving Caves – but I found this one to be very, very hard. I needed to make lots of “well, let’s see what happens if this square is in the cave” attempts. I suppose that’s what I get for avoiding solving tips!

    It was definitely a challenging Cave puzzle. I know I learned a few new tricks in solving this one. I used one technique in particular again and again while solving, and if I hadn’t clued into that technique, this puzzle would have been absolutely brutal.
