A custom Bloons TD Battles client
This client connects to the ninjakiwi servers. As you can see when you browse through the source code, they invented a funny protocol. Messages are just plain text, with commands like GimmeUrPlayerInfo. This client starts a quick battle by default, but you can also make it find a custom battle by providing a command line argument.
While in the preparation stage, you can see which towers the opponent picks. When the opponent spends battle energy to snoop your towers, they'll see 5 monkey buccaneers :P
When the game has started, this client sends a message through the chat, telling the opponent what to do. They are supposed to send commands to the bloons terminator. Some people seem to not understand what they should do, and surrender, even though they could easily receive a win by sending the /surrender or /disconnect command through the chat. Other people are more intelligent and send real commands to the terminator. It's always fun to see how surprised and amazed those people are. Sometimes they say that they're going to report you to the ninjakiwi staff, but since this client doesn't even need an account to connect to the servers, they can't ban.
The game usually ends when the opponent dies or makes the bloons terminator /disconnect or /surrender. Sometimes they send a ZOMG at themselves early and die quickly. Sometimes the opponent plays more than 30 rounds though.
