Wow, I really enjoyed this! The "hup" "plonk" sounds are cute, and I like the bits of narration. I did run into some technical issues, but the fact that you did this in one day blew my mind. I ended up finishing the sorting in 5 minutes, then spent 2 more minutes trying to find my mistake before figuring out that my first two books were "Bass" followed by "Bartlett"... Way to make me look the fool! :D
