I have a little issue with the sound. I have echoes, it's quite disturbing.
I thought I would be the only one having this issue! I'm experiencing the same echo effect.
The echo effect which usually only applies when visiting areas like caves is applying to every area and every sound in the game, including music and even the start menu.
When entering caves or the like, the echo effect is applied twice which results in more ugly sound.
Even when turning down all sounds in the options menu to zero, the echo effect of the muted sounds still plays.
