No you should definitely start with 2. Are you not somehow accidentally playing version 0.1? The download is now 280+ mb instead of 130
Maybe it has something to do with the app and/or having played 0.1? Because i most definetly updated the game
Did you load a save from 0.1? If you are getting the new home screen with images and outside view with an interactive map all is good.
Nope, probably has to do with the way the itch app updates the game or something like that
