It uses no OBB, but does attempt to download additional data files to its own com.snkplaymore.android003 directory in user storage (alongside DCIM etc). The source servers are long dead, but if these files are present on the local device and the test.dat save file in data\data\com.snkplaymore.android003 records that they have been downloaded, then further internet access isn't required.
