Poor execution, no mute button.
No instruction on filling out the whole board with cable.
I accidentally moused over a completed path and it got erased.
It would be better if you didn't have limited moves. Incidentally, a clock icon is misleading. It even gets counted if you scroll up a wall (and lay no cable).
Unlike link-a-pix, you can only link from one end, else you lose your line. Coupled with the limited line is bad.
