I really enjoy the "look" mechanic (it reminds me a little of of The Fall), but what's present in the game at the moment feels like it has some room for improvement.

Firstly, it feels like looking could be more precise. In this screenshot, you can see interaction 3 nodes are highlighted. Intuitively, I'd expect the node closest to the middle of the cone to be used when pressing E, but the outside the view cone is used.

It would also be nice to have an indicator to show which interaction node is going to be selected when pressing E if there is more than one node present within the viewcone. The "active" node could be made larger, or have different line thickness.

Finally it would be nice to  have a different visual representation for when the player is within interaction range of a node, so that before pressing E, the player will know whether they'll see a description or bring up the interaction wheel.
