Love it! The idea of matching the sounds works, the art style is clean and simple.

It could have been nice to let the user understand how the sound they pick is different (was it close or far?), and enabling them to hear the cat that actually would have matched.
And even though it's clearly written to click on the bottom right once your selection is done, i ended being a bit lost for a moment after selecting a cat (I was in fullscreen).
