Genuinely, this app is quite RELAXING; It FEELS LIKE HEAVEN, it's quite PEACEFUL, I also played it's music with a piano! But the best part is... ZEN MODE!! I have a problem though; when I press the menu/settings button, nothing shows up... it's all blank, but the other settings are NOT blank. Can you PLEASE fix this? I'll rate it 5-stars if you do : ) ; )
