Hacks
I installed this hack a few days ago. It was working perfectly fine until it wouldn't let me play moomoo.io. My brother can still play because he didn't install this hack. Do you know how to uninstall this hack??? If you do, please tell me. I'm getting desperate and I want to play! Please help.
