Wait is the song a recording of you playing guitar!? SUPER COOL. I also love that you have two modes, the chill mode and the "no birds allowed". One addition that would be nice is to see my score live when I'm playing no birds allowed! I got to 182 final score on my first playthrough, now I'm just letting it run to listen to the nice guitar and watch the birds swim in the pond in the chill mode :)
Edit: love how it keeps the high score on the main menu. I played again and got 247!
