The game used to allow free draw, where you can draw the ropes however you like. I realize that it would cause the same shapes to be drawn, but you at least had the option to play around a bit.
Now, you’re limited to exact points. What’s worse, is that on my current level, 33, the points are too far apart, making it practically impossible to pass. I suppose I can just cross my fingers and just retry until it randomly works, but yeah, the game is broken now.
