First of all the music is AMAZING!!!! I absolutely love it. However, as this is an idle please make a way for us to mute or lower the sounds/music. Thanks!

Not sure where else the put this... thought I'd report a demo bug. Putting down a colored circle, putting it in an upgrade circle (2 charge of the same color like 50% points), removing it a bit after charging, then putting it back a bit after charging makes it fully charged... but appears to break it entirely (I stopped gaining circle levels)...
