Very nice game and effects! Took me a few tries to get proficient enough to not die in the first pit and I eventually beat the game. I found myself spamming space, maybe as an idea have the echolocation be automatic every second or so? To spice things up a little bit

Everytime the player pings, it traces some rays to get the distance to all of the different colliders around. It uses this to build a mesh like this 
, with collisions coloured white the closer to the surface, and grey if there was no surface in range. Then it's just a shader which only colours in pixels if they are either in a expanding ring from the center, or if the ring has passed them and the pixel was white.
The better way of doing this would just be to use a particle system that has no gravity, is emitted all at once, and collides with the terrian, but Godot doesnt have particle collisions yet, and i couldnt be bothered learning a new engine

Oops, you're right, just fixed it. Anyway, i love your game, the idea of an audio only game is so cool.
The way the effect works is pretty simple, it just does a bunch of raycast to generate a mesh which is coloured so that where it hits platforms it's white, and then just does some shader magic to generate the rings, based off the mesh
