R2 Sashigane: In the example puzzle, the grid lines are presented as solid lines. Will this also be the case for competition puzzles? It's far better to present grid lines as dotted lines in region division puzzles.
R3 Muddy Creek, Go (etc): Could you make swapping Xs and Os allowed (as in Puzzle GPs)?
R5 Multi-Skyscrapers: How exactly is the partial scoring system going to work?
R6 Gokigen 3D: In the example puzzle, topmost three cells are divided incorectly. Division seen in its solution is correct.
(R8 Railroad Tracks: Answer key with Ls and Xs feels a bit cumbersome, why isn't it consistent with other loop puzzles?)
R8 Masyu: If a grey circle is used by both loops, should it be a Masyu circle for both loops? Or is it allowed for one loop to be neither?
R8 Railroad Tracks: What happens if two loops intersect in a cell adjacent to a clue not belonging to a circle? Does the number represent the total in such case?
R10 Curve Data: The text says that for the answer key enter the lengths of the segments, but in the example answer key ("23, 32"), numbers of cells belonging to segments are counted. Which of these is correct?
