Genre Spotlight 60: Mukkonn Enn (Puzzles 378 and 379)

Today's genre is Mukkonn Enn, first appearing in WPC 2017 as an instructionless puzzle. Prasanna Seshadri refined the genre (e.g. made it a full loop) and changed the name to Mukkonn Enn for its 2022 GrandmasterPuzzles debut.  I've seen this type for a while but never got around to making one.  Acting on those hunches is what this spotlight series is about, right?

Rules: Draw a single, non-intersecting loop that passes through the center of all cells, including clue cells. Each clue cell is divided into four sections. If a number is present in a section and the loop travels in that direction, then the number represents the length of the straight loop segment in that direction, measured from the clue cell to the cell where the loop turns. If the loop does not travel in that direction, then the number means nothing.

                 

Two puzzles today.  The first puzzle uses maybe an overused theme, but it works decently well in this genre.  I also tried to see if all clues could be 1 or 2 and succeeded, though it did take some effort.

This second puzzle was designed to showcase a particular logical step.
