It really sad that AAG has been removed from Google Play due to developer shutting it down
The good thing is that there is a game called 'Otogi Spirit Agents' that is pretty similar with AGG (except the gameplay is different compared to the AGG)
Otogi Spirit Agents is still up in Play Store (i hope it stay that way) . So you can search it up on Play Store and download it if you want to.
