super addicting and cute game! i'm a little dumb, so i think it's my fault, but I cannot for the life of me do the encased relics lol
It's like a metal detector, almost. The larger the circle and louder the noise that comes from it, the closer you are to the correct spot. Usually, I get a bit lost with which direction you have to go, but if you try to space out in the general area of where you're getting the closest signal, you might just hit it.
Sorry, that's the best way I could explain, good luck :)
