I've thought about doing games based on echo-location before, so it's cool to see someone else's take on it! I would have liked to see mechanics based on it, as the current state is nothing more than being a bit inconvenient to walk around, but I know that time constraints get us all.
The game looks very nice, the art and sound design working well together to create a atmosphere for the player.
The story was very abrupt and short which I assume was due to time constraints. It could use some proofreading though as there were quite a few typos.
I liked how everything in the game very politely waiting for you to finish reading and to "see" what was going to happen with your snapping haha.
Great job finishing the jam!
