Walkthrough for yesterday's Guide Arrow (Aqre): https://youtu.be/PcIbn--b4yE

I'd like to introduce you to my most recent obsession: Crosswall. It's a loop genre invented in January by Japanese puzzle author MrSolyu with an incredibly rich variety of logic. This is another genre supported by the Kudamono Editor, but I've also included Penpa links again. If you'd like to see more of Crosswall, MrSolyu just wrapped up a month-long tutorial series on Puzzle Square today: https://puzsq.logicpuzzle.app/?sortType=time&sortOrder=ASC&hashtag=174

Rules: Connect some pairs of orthogonally adjacent dots to form a single loop. Two perpendicular line segments may intersect each other, but not turn at their intersection or otherwise overlap. The loop and the grid boundary divide the grid into regions. Large number clues indicate the total number of cells in the region they are contained in. Small number clues indicate the minimum number of times one must cross the loop to trace a path from the clue to the outside of the grid.

I've made sure that the puzzle is still approachable knowing only the rules, but here's an extremely powerful GAPP 101 in case you'd like another perspective: Crosswall gets much easier if you shade cells based on whether their "Crosswall number" is odd or even, similar to how shading can be used in Slitherlink. I'll also show how to do this in tomorrow's solution video.
