Unless I'm missing something, this seems to be a very simple game where you and an opponent continually play rock, paper, scissors, over and over again. While I do wish I had been given a bit more to do, I'd be lying if I said that I didn't find the game to be somewhat addictive.
It did take me a while to figure out how to actually challenge my opponent. The game did not recognize the command "play" or "challenge." Finally, I got frustrated and said, "Hit Opponent" and that turned out to be the command to go with.
