Good, but …
Response from developer
My apologies! I wrote the music myself years ago, and I agree completely that it is loud and repetitive :) In the latest version of the app, the music has been replaced with music that is more professional than my own, and there are now buttons that allow sounds to be turned on or off. Simply tap the "Turn sounds off" button on the main screen, or the "Sounds" button when playing a puzzle. I hope this helps. Thank you for the review/feedback! -Ryan
