  • Further redesign of all arrows to improve legibility at smaller resolutions
  • Shading aux marks added
  • arrows in multiple directions can be added/cleared simultaneously (this required a reencoding of all puzzles)
2023-08-06 Line highlighting was disabled, since it was more distracting than informative. At the same time, small dots were added to mark incorrect directions lacking an arrow - thanks Eli Doris (TwoHoleStraw), and others who have hinted at that in past! 2023-08-08 Added classic sets by Mitchell Clarke (DireKrow) and Ben Woodley (Rubrica), plus a reference to hypermetropic pentominos (dohz, Martin Ender (Menderbug)), and added line colour variegation as well. Thanks everyone! 2023-11-20 Myopia and Hyperopia added as standalone variants, for square grids 2024-03-01 Neatly modernised panels were crafted by Eli Doris (TwoHoleStraw).
