This game is an absolute perfect game for a zen like atmosphere. The art is incredibly well done it is minimalistic art style.
As for hooking up the phone lines. It should have been really simple. Knowing how it works make the game simple. But not knowing the game makes the game and absolute infuriating mess. This should be made easier and more polish for ease of access.
One thing that I don't understand is the implementation of dead ends and poles that lead into nowhere. A game like this with its zen like atmosphere doesn't need this kind of obstructive puzzle mechanics.
