Long story short, I made a retro Pong clone and submitted it to the App Store as my first app. It survived for a bit, but I eventually received a message from Atari tell me to remove it. There was nothing more than that, I just took it down, and they made no other demands. Since then, it has remained removed.
I have become a much better programmer now and would now like to re-create my original app and upload it again. However, I'm afraid that something of the sort would happen again. Is remaking the game itself against any laws? If not, would using the name "Super Ping" instead of "Super Pong" be legal?
