Puzzle #129: Contact

I've given this genre another go. I think the 1 through 7 theme worked out pretty nicely. The opening of the puzzle is easy, but it gets a bit harder towards the end.
For everyone who's been trying to get to this post yesterday from other blogs, I'm sorry. I accidentally forgot to add the scheduled time.

Puzzle #89: Contact

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.
