Really neat idea for a puzzle platformer and it fits the task perfectly! The level design is great, I like how I have to make myself a path first and then focus on the sounds.
My only feedback is that a tutorial at the beginning would be helpful and that I didn't realize at first that there was no sound requirement in the last room, so I lost some time there.
Also, I have no idea how this game is "metroidvania-inspired". But still, a very cool entry!
