[Q] Restoring Monster Strike from a root backup

Hello guys, I am a player of Monster Strike (MOS) Japanese version, and just having flashed a CM 12.1.
I have a backup of MOS by J-rummy’s ROM toolbox, however MOS disables me to recover.
MOS needs us to backup only by G+ and I have no backups to my Google account.
Have any guys also attempted to recover MOS by a root backup? Thanks interacting and reminding.:)
