It takes the Theme literally where you literally connect the plug to a socket. There are some puzzle elements to it but not too hard. It seems that all models in this game are custom made which is impressive. (correct me if I'm wrong)
Also in the menu, I like that you can slightly move the camera with your mouse position.
One criticism is that sometimes the walls are blocking the camera. Maybe can be further improved by adding camera collision with the wall and make it transparent when it is blocking the view.
