I've always liked drawing, but never considered myself talented, so thank you for your kind words 🥹 and for playing my game!
I actually thought about the Rorschach Test when trying to come up with ideas =D
I see what you mean about checking the mouse hold and for the game jam build I deliberately set pieces to snap in place as soon as you move them close enough, because I thought this would feel more satisfying... And also hoped that rotated pieces will prevent full-on brute forcing lol But I'll test how your suggestion feels for the post-jam update! Thanks for the feedback!
