I have some suggestions

This game is off the charts amazing, although the song that they play gets boring after a while. Maybe you can change the song so that adults can enjoy it, because it sounds like a lullaby. Also, the character that sort of looks like a balloon that makes a squeaky sound bothers me a lot. Please take it away and replace it with a better one. Speaking of that, please add more characters to choose from. And a recording button. Please try to do as much as possible in the next update.
