There is no actual game content update, the added volume is the material and code for the second level, but it has not been implemented. So you can use the previous version. This is my first official game, so please let me know if you are unable to return to the previous version. The operation is to select the game version in the settings
The main purpose of updating this version is to explain the source and legality of game materials..If the sharer is unwilling for me to use the material, I will delete and adjust the game content.
