Hi, Demeter,
Yes, clue set 11, reading right to left, clue set 25, reading left to right, and clue set 10, reading top to bottom. Also clue set 16, reading bottom to top encounters no obstacles.
Buzzb has provided an illustration of glancing contact in an earlier post. If a corner of an answer is also the corner of an obstacle cell, with the obstacle cell in the adjoining row or column, then the answer does not continue in the same direction but goes off (away from the obstacle cell) at a 90-degre angle. In some clue sets,there are several turns, but every clue set ends at either an obstacle cell or at the edge of the puzzle.
