Nice little game ! It was a nice and enjoyable little game =) ! The art is simple, but perfect for this game, and your concept respect the theme =) !
I have three main critisisms :
- It's really perturbing to have to connect the cable on the "right" side. Normally, cables should let the current as long as the cables are connected, without caring for its direction.
- Probably an effect of the first point, but I don't understand why the cables glow once in the correct place. It's not a puzzle if you give the solution right away =). But I must admit that, with directional cables, it would have been impossible without.
- No music =). I would have enjoyed a little background music =)
Otherwise, that was a nice idea, congratulations =) !
