Will keep in mind! You’re right in that the shapes are actually randomly generated, so you can’t find an exact match. Since the jam is nearly over, I might as well reveal the scoring metric: It computes how well you’ve filled in the area of the hole while not letting it overflow out of the shape rather than comparing vertex positions. This is a bit un-intuitive since I initially design it to be a precision puzzle to match the shape exactly but ran out of time. I will definitely keep in mind the suggestion about combining shapes. Thanks for sharing your thoughts!
