Composer Originally Being Free

Near the beginning of Composer's text file, there is text that says:

PLEASE NOTE: My Singing Monsters Composer is free to play, but charges real money for additional in-app content. You may restrict in-app purchases by adjusting your Google Play account settings.

This means Composer was originally going to be free with in app purchases (Example: Rares Pack, Dipsters, Ethereals Pack etc.) until they decided to make it cost money and make stuff like Dipsters, Rares and Ethereals be free.

The Google Play billing service is not available at this time.  You can continue to use this app but you won't be able to make purchases.

Your transaction was not completed.

My Singing Monsters Composer is free to play, but you have the option to purchase extra Diamonds, Treats, or Coins. These items cost real money and will be charged to your iTunes account. You can adjust your device settings to lock the ability to make in-app purchases.
