Well i just tried :
I can connect my google account with my unsigned apk , nice , but the enemy hit something like -1111010101 damages ^^ . Look like it's patched :( .
Thanks a lot :) !
Moreover the development of the game is stuck since 2015 ( v1.5.3 ) and they are a really Small crew working on it .
So creating a new hack / back UP this one could be usefull for everybody :D .
PS : hacking Crows is risky so even if it's a modded apk with No Cooldown , fix...
