Sudokuvania 2: Lineage of Logic by Skeptical Mario
Ever since he disappeared in a Sudoku attack, you have had questions about your father's fate. Now that the mythical castle Sudokuvania has reappeared, you know the answers must lie somewhere within.
Introduction
This is, obviously, a sequel to Sudokuvania: Digits of Despair. Even before publishing that puzzle, I knew I wanted to make another giant sudoku puzzle that played like a Metroidvania; I think I'd be happy just making these things until I keel over. But one thing at a time. This is the second game in the Sudokuvania series: Lineage of Logic.
Sudokuvania 2 continues to bridge the gap between video games and pencil puzzles. As in the previous game, by clearing the dynamic fog, you will reveal the rules that apply to each grid of the intricately connected puzzle. Some rules are portrayed as quests, and some as inventory items, but most will be familiar to those experienced in variant sudoku.
Notably, I tried to implement variable difficulty in the form of optional clues. In addition to the difficult boss puzzles, optional enemy puzzles can be played to learn a digit and bypass difficult logic. In addition, one ending to the puzzle's quests can be reached without completing most of the grids. Play however you like!
Compatibility
Warning: SudokuPad is not optimized for very large puzzles. Make sure the setting "Experimental > Test Large Puzzle UI" is ON (the bottommost setting option in the menu). Zooming and panning is not supported for mobile devices and may not work properly in all browsers.
To zoom, use the mouse scroll wheel or, on a Mac, two fingers on the touchpad. To drag, hold down the right mouse button.
Rules
Complete the Quests by filling cells in each grid according to its rules. Completely filling all grids is NOT required to reach an ending of the story.
Sudoku - Unless overridden by an uncovered rule, you may assume that each grid follows normal sudoku rules: Place digits from 1-n into each grid, where n is the grid's square size, without repeating in a row, column, or box.
Dynamic Fog - Entering a correct digit into a cell will clear the fog from that cell and perhaps others.
Dynamic Rules - Additional rules will be displayed in this panel when certain cells are selected. Abridged rules are also displayed on the map itself. These rules are only valid if the selected cell is NOT covered by fog.
Play the puzzle on Sudokupad (desktop only)

I hope you enjoy the puzzle! :-)
Immense gratitude to sirxemic and Sven Neumann for creating the tools that made it possible for me to set this puzzle; special thanks to cirne for their json post-processing script which enabled the dynamically-updating rules; and everyone who tested and gave feedback during the months of development.

The difficulty of the Sudoku section this time is much lower than the previous one.
'Stalking the Freezer' is the only one that makes me feel like the difficulty can keep up with previous bosses
Regarding the parts beyond Sudoku, the difficulty remains the same as before, especially in the later stages.
Speaking of which, I recall that during this period, someone created fan works, and I don't remember the difficulty of those being particularly high. However, I think this is normal. After all, with so many bosses, each representing an independent Sudoku puzzle, it's impossible for the difficulty of every boss to match that of the previous one.
The above is the true feeling of one of the problem solvers.

is the shop supposed to stay hidden even after you unlock its door,because i can't see any of the wares even though i reached it and im unsure if its intended since im having a hard time finding the next step after finishing that questline
edit:nevermind it took me 3 days to notice that i missed some interaction between 2 particular grids

Regarding the rules of BOSS "A Night's Tale", they are not very user-friendly for problem solvers from non-English-speaking countries.
Suggested addition: The positions of the stars are solely for aesthetic purposes.
And: the galaxy is 180°-rotationally symmetric about itself, not about R5C5.
Regarding the rules of the blink bracelet, if anyone doesn't understand at once, it means that among the four directions (up, down, left, and right), the indicated direction is the closest N.

In the boss "A Night's Tale", the 9's galaxy is seems not center-symmetry; and in the boss "Through the Ringer", the rule of Graplling Hook should be corrected as "N is the value of the tip's cell"

Absolutely amazing sequel, loved the theme of the grids and the bosses, those last few ones were immaculate. Loved testing this, can't wait to see what you may do next!

I have already played the first Sudokuvania before.There is no doubt that both puzzles are carefully designed and full of amazing details,which always force me to think a lot and finaly reach the answer.It's such a nice experience to fill in the cells with the digits.I can't find words to adequately describe the feelings when I go through the last few areas,maybe it's the power of logic.

I'm not a regular sudoku player, but I did get to the end of the first Sudokuvania and have been looking forward to this one for a while!
For what it's worth, I found the description for the 'hot' area slightly confusing in its brevity. I'd not encountered this variant before and needed to do a fair amount of googling to understand both what the variant is usually called and then what the implications of the rule were.

Rarely does finishing a puzzle give you the same satisfaction of finishing a long fantasy book series, I can think of few such puzzles and this certainly belongs on the list.

Answer: Every cell the quest lines enter is in a grid where digits must be entered.

Quick question: Quest lines can't exit the grid, but can they cut corners? I'm trying to determine in Grid 02 if the quest line could move from r9c8 directly SE into the next grid cutting the solid black corner or if it's forced to go into either r9c9 or r8c9.

Hello! I have a question.
Quest lines are stated to remain within the bounds of the grids; does this allow for them to cut a corner? e.g., going from cell A diagonally down and right to cell B, where the cell below cell A (and to the left of cell B) is outside the grids?
