I make a lot of loop puzzles. Loop puzzles just come more naturally to me. This was actually an idea I had been working with before, till I also found it on Naoki's website. There's 2 more ideas I saw there that I had actually tried to work with myself. Both ideas I couldn't really get to work properly, but Naoki proved me wrong and his puzzles in those genres are actually very nice. So I might give them another go some time.
This puzzle isn't as challenging as the last one. So you can relax a bit more this with one.
