A powerful concept, with a really clean presentation! I was really surprised by the style of the game. I've already seen games playing with the windows, but I didn't know that you could actually do decent elastic effects!
I also enjoyed the minimalist approach to rhythm game. It makes the game precise, but easy to read. Although I did notice that it was slightly out of sync, at least on my device. I had to play off-beat, one eighth note in advance. Which, once I got that, was kinda playable.
Another side note: I enjoyed the game visual identity, but found these meme kinda out of place. :p I guess there wasn't much time left for those screen.
Congratulation for making a game with such a strong identity and concept!
