Acknowledgements and Changes
2021-09-10 Thanks to Sophie (Edderiofer) for suggesting the vertex aux marks, and for alongside Wessel Strijkstra finding a transcription error in the first puzzle, now corrected
2023-12-15 A typo found by placeholder was corrected.
2024-02-01 A recent regression found by PinkHoodie in some knight genres was fixed (cause: former flaw in template inheritance model)
2024-03-09 Extra corner OX aux marks added; restored double-diagonal vertex marks (now with input unit tests), corrected a dragging bug where in certain situations a mass of self-crossing lines was generated.
2024-03-09 PinkHoodie crafted two puzzles, one (Thread of Absent Thoughts) for Enigmarch day 9!
2024-04-03 Highlighting was upgraded, to bring it in line with other sight genres. Thanks PinkHoodie help avoiding a regression.
2024-06-11 A regression found by PinkHoodie (making adding numbers impossible) was corrected (cause: incorrect number templates after changing to the number dial)
2024-07-20 Collision behaviour for circles/arrows (PinkHoodie) was corrected (cause: June collision update)
