This is well put together as an audio exploration experience! I loved your explanation on the wall; I need something similar for my entry.

The keyboard on the floor to control the looping audio was a nice touch! Have you ever played The Talos Principle? In it, you control your character as a recording, then hit replay so you can control yourself and a ghost of yourself moves around as recorded. It would be cool to have some player-defined audio loops based on a second character moving as recorded by player control.

Pretty cool little virtual piano room!  Nice work on the extra options too.  Keys would feel more reactive if they changed color or moved a little when played but works well enough as is -great job!

I am unable to play :( I downloaded the windows version, the logos show, the title screen gives me the option to "begin" but not matter how much I click nothing happens. :( I can click "quit". I was looking to remain silent to see what happens. :P So my rating is based on what I saw on the youtube video. It looks like it would be a nice fun way to jam out or relax while listening to music. 

It's a pleasant little music toy! Nice selection of samples. Some kind of an objective would be welcome, like a method to escape from the room by performing some series of musical tasks or miming a tune or something :)
