We are happy to announce that the upgrade store is complete. We will continue to make improvements. All of your data is being moved to the cloud for security reasons. We worked hard to establish a secure connection with PlayFab and Steam so you can keep all of your upgrades no matter the device you use. If you have any issues please feel free to reach out to us. We want to ensure everyone has a great experience moving forward. We are about to scale the game very rapidly so stay tuned for more updates. We want to thank everyone for their support.
