I think there's a version of this that gives some hint like a riddle to help the player just a bit. Something that gives very loose shape or form hinting in its solution. Aside from that, this plays solidly. I liked the touch of how the needle works. I could suggest using a tween with easing for it would make its follow of the mouse cursor look buttery-smooth, that is if it's being rotated rather than using different frames for each angle.
If you're ever interested in a collab on a jam, let me know!
