As Halloween is approaching, I wanted to do a puzzle based off one of my favorite horror movies, The Descent (2005, UK). The film takes place in a cave, so naturally I had to make a cave puzzle. The brown lines look like the drawings the characters find on the wall, convincing them that the cave has a second way out. The crimson line represents their path through the cave, and as you can see, they descend further into the depths rather than escaping through the other exit. Comments and ratings are much appreciated, and please check out my other puzzles here. Feel free to post a hidden comment below or message me on Discord if you'd like any help! Enjoy!

Rules:

Normal Sudoku rules apply. Digits on a brown line form a set of non-repeating, consecutive numbers (in any order). Any set of three sequential cells on a red line contains a low digit (1-3), a middle digit (4-6), and a high digit (7-9). Digits given in a small circle appear at least once each in the four surrounding cells.

Cells are either wall or cave cells. Low digits belong to one group, high digits belong to the other, and a cell with a middle digit could belong to either group. Walls are orthogonally connected to the edge of the grid and the cave is one orthogonally connected area. A 2x2 area cannot be fully wall nor fully cave cells.

A digit placed in a large circle indicates the number of cells of its own “type” (i.e. cave or wall) that it sees horizontally and vertically, including itself.
