Somehow, there are three totally different versions of this game and this version is totally different from the 2016 and 2017 versions. Thus, this is the 2014 version. The "Rebel Mode" has been activated, which unlocks the final two levels. Originally, this game used an advent calendar system with the "rebel mode" seeming to activate after the final day (when the full content was released). If you want to disable that, set rebelMode to false in data/config.xml
