It's an entire philosophy of bot-dom. UpBot is at peace with its purpose in life. It is UpBot. It goes up. It doesn't try to be something it's not. If UpBot needs to go left, then LeftBot is going to have to help it. The makers describe the game as "elegant," and that really is an apt descriptor for the solutions. When you figure it out, everything works together like clockwork. It's the figuring out that's the challenge, and the fun.
