I've made a more in depth video showing this mechanic with sound: https://www.youtube.com/watch?v=uUCB189Om9s
I think sound gives just the right amount of help to get you in the general vicinity of the next clue, without completely giving it away. Of course there could be lower difficulty levels with visual indicators as well.
I will definitely be adding a tutorial since the mechanics are so bizarre. I was also going to add an additional mechanic: it's not just about moving a specific object, but also placing an object within the vicinity of another unknown object.
