2025-01-05 Thanks PinkHoodie for finding a weakness in the algorithm for region (loop) fusion, meanwhile corrected, before the release, and for suggesting a clearer quadrilateral symbol and stronger highlighting of incorrectly-shaped regions. 2025-01-06 The rule panels for Sample Paint were crafted by PinkHoodie, who also sent the cover pic and transcribed the puzzle used to ensure the ruleset was correct. Thank you! 2025-01-07 An edge-case sent by PinkHoodie was corrected (cause: not considering the case of inner loops) 2025-01-12puzzlettersPinkHoodie mailed 2 Sample Paint (classic) puzzles - धन्यवाद!
