I made this puzzle on a whim and didn't realize it had mostly the same ruleset as a recent Sandra and Nala puzzle (my subconscious must have been influenced in some way I guess) so definitely check that out too if you haven't. Hope you enjoy! Also I'm not entirely sure about the difficulty, it might be closer to 2.5 or even 3.

Rules:

You got lost in a cave and now must find your way out!

Normal 6x6 Sudoku rules apply.

Shade some cells such that the unshaded cells form an orthogonally connected region (the path). All shaded cells (the cave wall) must be orthogonally connected to the edge of the grid. There may be no 2x2 of unshaded cells, but there may be 2x2s of shaded cells. Any shaded cell is greater in value than any orthogonally adjacent unshaded cell.

A lightbulb is always on an unshaded cell and lights the way along the path. The digit in a lightbulb cell shows how many unshaded cells that cell can see orthogonally, including itself (shaded cells block line of sight).

A white stone separates consecutive digits. Not all stones are necessarily given.
