I think all of the character designs and art are incredibly clean and they all fit perfectly in the style, I'd say my favourite detail is the metronome-ish sort of ticking in the music which corelates really well with (what I assume is) the main characters bigger clock/timer eye. Another thing is how unique each character is, having multiple pieces of dialogue, and having their own unique sound effects when talking.
Overall I really enjoyed the personality, the effort put into the environments and the substories that link some characters together. Great Job!
