Puzzle #39 - Look-Air

On account of three of its eight clues being 5s, this puzzle is, as you might expect, on the easier side. It uses some deductions characteristic of the larger squares that crop up naturally when you have 4s and 5s.

Rules

Shade some cells so that each orthogonally-connected area of shaded cells forms a perfect square. Clues may be shaded, and each clue represents how many cells are shaded from among the clue cell itself and its orthogonal neighbours. Two shaded square areas of the same size must not have an unobstructed run of unshaded cells, horizontally or vertically, anywhere between them.

Difficulty: 2/10
