Genre Spotlight 54: Ice Walk (Puzzles 366 and 367)

Today's genre has started to gain some popularity in the wider puzzle sphere, but is still niche enough that it probably works for the Spotlight.  Ice Walk is a Nikoli genre that didn't really take off until it was ported it to puzz.link several years later.  This type is very good, and I'm glad it is getting the recognition it deserves.  (Please, Nikoli, make a sequel to the Omopa collection!)

Rules: Draw a loop through the centers of some cells which passes through each numbered cell. Two perpendicular line segments may intersect each other only on icy cells, but they may not turn at their intersection or otherwise overlap. The loop may not turn on icy cells. A number indicates how many cells make up the continuous non-icy section of the loop that the number is on.

          

Two puzzles for you today.  The first one is a bit silly.

The second puzzle was an attempt to create a grid with a more "open" structure.  When first designing Ice Walk puzzles, I became a fan of "corridor" structures for givens, where the dry cells form paths of width one that snake across the grid.  More sparse layouts of ice cells, on the other hand, are much less natural to think about.  This puzzle came out well, but the break-in may be hard to spot.
