Thanks for playing the game!
I don't mind the suggestion and I've been thinking of a way on how to fix it but to no avail. I was detecting interactable objects differently by using Raycasting than the normal Unity way of using Rigidbody and Colliders so I'm not sure if the OnTriggerEvent will work so interacting with them around the sides or especially the corners are a bit hard. I wanted to try implementing a UI notification when interacting with the switches as well but didn't have time since I was barely able to make the audio feedback work properly. Still, thanks for the suggestion and I'll see if I can try to improve upon this!
