I had actually thought of this idea myself at first. I figured it would be the logical combination between Slitherlink and Line of Sight. I couldn't really get them to work very well though. Then I spotted the same genre on Naoki's website. After doing his puzzles I got a bit of an idea how to work the genre properly. This first puzzle has some standard deductions concerning the corners that you'll need to learn to solve these puzzles.
