A row/column/diagonal can be moved if and only if

1. the number of pieces currently in it is the same as the final number of pieces in it (which can be viewed by pressing q)
2. all pieces in it are contiguous (in other words, touching each other so that there are no gaps in between)

Keybinds:

• Q = Show Target/Goal State.
• R = Reset current level.
• Space = Switch selected Wire orientation (cycle between vertical, horizontal, diagonal).
• Arrow Keys = Select and Move Wires.
• T = Show Timer (Elapsed time).
