Great work! Very solid entry with great polish. It felt fun to try to challenge myself by hitting the arrows as quickly as possible. I would suggest that maybe having a smoother transition from arrow input to next level would be better, and also some instruction about hitting arrows in order (though the main menu does provide that); I thought you had to hit them together my first time through and lost because of it. I also liked the background switching and keeping the high score! Great job again!
