When the game was released, you had to pay to download it and also pay within the app to unlock the full game. It wasobviously a mistake on our part, and we are currently refunding all players who purchased the game twice. You will be refunded by us automatically!

The app is now free to try, so you can download it and play the first levels for free before deciding whether to purchase the full game. If you're still seing the game as a paid app, please close and reopen the Play Store! Clearing the cache of the Play Store could also help.

We apologise for the inconvenience!
