this happened to everyone, not just you. He may took it down because it's not for android, it has many bugs, he's testing it. And it mat have to be delayed because he's making birthday bash mode, the school homework also slows him down (mentioned in gamejolt). He might also be taking devlopment breaks that slow him down ALOT more!
No, when I was talking to Alex he said do u wanna play but when we tried to play I couldn't join. It would just say the same failure message over and over and so Alex said its bugged.
