Is this a virus, I downloaded it on a mac and it said
“AnotherChance” cannot be opened because the developer cannot be verified.
macOS cannot verify that this app is free from malware.
The game is not a virus its just letting you know that whatever your using is unknown and just tries to protect you but if you got to
System Preference and then click on security and privacy you"ll see toward the bottom of the screen that you could override the command and open it which will give you some last precautions and then it will open the game
