Though you did make it in 2 days...
You still should have added several things to it before submission. Like, an ending! After playing for about 10 rounds, and winning 10 to 0, I decided that the game would just go on indefinately. So if there is an ending, you made it way to long. after about 5 to 0 or even 10 to 0 you should "win" and beat the spammer permanately. The whole game over you won good work kinda thing. And Hard, should be hard. It isn't.
