Nice video. I am not sure about the light beam. It seems too in your face. So instead of exploring, I expect many player will go route one to these beams.
Without knowing much of your game (so I am making wild guess), Why not make it more exploitative. Instead of a ray of lights, maybe a clue like “its between a well & a river”, & there are sound or visual clue as you get near to uncover the secret.
