I started playing solo chess lately, but sometimes i get red ticks (i've solved the puzzle, but in "wrong" way). They take off correct answer or streak, i think that if puzzle is solved, no matter by correct way or another, it should be a plus point, not minus.
Wait but it's impossible to take more moves than the best solution bc you make one capture with every move. Have you been using the "undo" button? Using it gets you a red tick.
