Very hard for me, 86 minutes, with quite some mistakes. Took me very long to understand where the pressure was

**
Congratulations, simontherry, and thank you for your comment! I can get what you are saying. The lk math works quite differently than it would do in "normal sudoku".
Kind regards, sujoyku

4 hours over 4 days and 4 attempts! Definitely a 5 star for me. The break-in discovery was beautiful. Very well designed and fun, thanks!

Very interesting, with the first half the most difficult part by far. Thanks for setting this excellent puzzle!

Very nice! 3 stars for me. I don't get difficulty ratings on LMD; this one isn't much more difficult than The Great Divide that got 2 stars.

**
Thank you for your comment, mscha! I am glad that you enjoyed the puzzle. Initially, I also had it at (high) 3*, but testing feedback suggested it was more reasonable to post it at 4. What concerns "The Great Divide", I think that one is underrated in difficulty, I still believe to be at least 3. Thanks again for sharing your thoughts!
Kind regards, sujoyku

Impressive how well you managed to execute on a theme here. It has a clear throughline, but doesn't feel anywhere near repetitive.

**
Thank you for your comment, Norkas! I am glad that you liked the puzzle. I indeed tried to be thematic (also for telegraphing), so I am very happy that this came over.
Kind regards, sujoyku

Very fun. I love this variant because it's very geometric and only a little bit arithmetic. You've done that very well here, thank you!

**
Thank you for your comment, E1gh7! To me, the puzzle is a mix of both geometry (Isofill) and arithmetics (little killer). I liked the interplay of them, so it is nice to hear that you enjoyed it as well.
Kind regards, sujoyku

Oohhhhh now I get the title. Very fun but tough, 4* for me.

**
Thank you for your comment, Dogfood! I am glad you had a fun solve. Considering difficulty, I was torn between 3 and 4, but ultimately posted it at 3. Thanks for sharing your take.
Kind regards, sujoyku

That was so much math @.@ But I'm proud of myself for completing it, even if I relied on the calculate sums tool far too much lol

Congratulations on the solve and thank you for your comment, yuripuppies! I hope you had a fun solve.

Vielen herzlichen Dank für dieses unglaubliche Puzzle. Ich war mehrmals überzeugt, dass ich es kaputt gemacht hatte, doch dann fand ich jedesmal einen schmalen Pfad, auf dem es weiterging. Fantastisch!

Sehr gern geschehen, Franjo, vielen Dank für deinen Kommentar! Es freut mich, dass Dir die Variante so gut gefallen hat.
Herzliche Grüße, sujoyku

Wow! That's a very nice puzzle, and a great take on Isofill. Took me about 30 minutes all up, but every step was a delight to find.

Exquisite setting! This was very hard for me once I got past the break-in (which was beautiful) - every cell after that felt hard-won, but ultimately fair. The logic in this felt very fresh, providing a wonderful interplay between arithmetic and geometry. Loved it

Thank you for your comment, marty_sears! It is great to hear that you liked it.
