I thought the audio touches were nice and enhancing them with the onomatopoeia particles was a really nice touch. I had a good time working my way around from the clock to the piano to the fireplace and what I assume is a window I could open and close. I kept searching and searching though, and I just couldn't find the key.
I'm glad I came back to revisit this. I couldn't get it to run on my Mac in HTML, but on my Windows laptop it ran no problem. This was a really unique take and a cool idea. Good entry.
