Very cool idea and visually and auditive well polished. The physics get a bit clunky from time to time but the puzzles are clever made and have a good introduction.
I would definetly rework the controls:
- Right click to unplug
- Automatic unplug, if I plug a new thing.
The way it is implemented, got me struggling a couple of times.
But very good and polished game. You should continue to work on that.
