This puzzle combines Entropy and Cavern Crawl logic. Special thanks to the pioneer of Entropy, Mad-Tyas, for inspiration, testing, and feedback. I highly recommend checking out his puzzles!
Rules:
Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.
Entropy: the low digits (1, 2, 3), the middle digits (4, 5, 6), and the high digits (7, 8, 9) form three distinct groups. Every 2x2 region within the cage must contain at least one digit from each group.
Climbing Ropes: adjacent digits along brown lines must have a difference of 3 or less.
You can solve online:

A very nice combination of the two constraints. It's a pleasure to see the family of entropy puzzles grow.
