This sudoku is intended to be the first in an April Fool’s series, hence the early publication date.
Rules: Standard 6x6 sudoku rules apply. Usual sudoku variant rules apply for the following variants: negative diagonal, sandwich sums, killer cages, maximum, minimum, even numbers, little killers, grey palindrome lines, purple renban lines, green German whisper lines, red column indexers, thermometers, V-sums (not all shown) and black kropki dots (ditto). If you’re familiar with all of those, you can stop reading, there are no “hidden tricks” in the rules.
Negative diagonal: digits cannot repeat along the negative diagonal (marked in blue).
Sandwich sums: Values outside the grid indicate the sum of the digits between 1 and 6 in that row or column. (Applies to values without an arrow)
Killer cages: Digits in cages must sum to the number in the top-left corner and cannot repeat.
Maximum: Numbers surrounded by “> signs” are greater than all orthogonally adjacent cells.
Minimum: Numbers surrounded by “< signs” are smaller than all orthogonally adjacent cells.
Even: Cells with grey squares must contain even digits.
Little killers: Digits along diagonals marked with an arrow sum to the number indicated.
Palindromes: Digits on a grey palindrome line read the same forwards and backwards
Renban lines: Digits on a purple renban line form a non-repeating set of consecutive digits in any order.
German whisper lines: Digits in a green German whisper line must have a difference of at least 5.
Red column indexers: A cell marked in red in column X indicates the number of the column where the digit X appears in the row where the red cell is placed.
Thermometers: Numbers on a thermometer strictly increase as they move away from the bulb.
V-sums: Cells joined by a V must sum to 5.
Black Kropki dots: Digits in cells joined by a black dot must have a ratio of 2:1.
Solution code: Rows 1 and 2 (12 digits, no spaces).

What a fun puzzle! I think I found this especially funny (and relatable), as I too tend to over-complicate things that are actually quite simple. :)

Lovely. I don't know why the rating isn't higher. Purists, I suppose.

Reply by Lorena: That’s very nice of you to say. Dont worry, if I cared about ratings I certainly wouldn’t do the things I do!

That palindrome doubles as a region sum

Enjoyed the visual humor, spent almost more time looking at the redundancies than applying actual logic lol

Reply by Lorena: Redundancies? What redundancies?

The thing about redundancy is that it's all about doing superfluous things in an unnecessary way that's generally optional.

Reply by Lorena: You can say that twice!

Ridiculous fun - looking forward to the sequels.

Reply by Lorena: Glad you enjoyed it! One of the sequels has already been qualified as “cruel” so consider yourself warned.

"Chocolate Teapot", I just knew this puzzle would have a you know what in the corner.

Reply by Lorena: I just had to.

What does redundancy mean again?
——
Reply by Lorena: Being no longer in employment because there is no more work available? Just kidding, I also hate it when people are redundant and say things twice.

occam's bludgeon: always pluralize if possible

What a fun! My fastest sudoku ever (3 min.) and I guess I never before had to laugh out loud while solving a sudoku. I especially love the long ruleset.
Thank you for brighten up my day!

Loved it, my favorite clues were the sandwich totals

Reply by Lorena: There’s something for everyone! Thank you for the solve and your kind comment.

Not sure why but out of all of them, the index cell made me lol the most. Can't wait for the next installment!
——
Reply by Lorena: That’s my favorite too, I think because it isn’t as immediately obvious as the others. Thank you for your comment, I’ll make sure to keep you posted!

New reply by Lorena: The next one is up, but it’s… let’s just say it’s not like this one at all.

Beautifully silly!

Funny little thing. This was a good way to finish my day. The given digits in row 4 were not even necessary. But maybe that would have gone against the theme.
——
Reply by Lorena: Thank you for your lovely words! I’d say those digits were about as useful as a chocolate teapot.
