Good... for free.
The gameplay is essentially very simple, and seems to be quite... well, nothing. It also fails to give any interpretable tutorial, nor any real tips during gameplay to help out the uninitiated, like me, and it seems that just by constantly hitting A at every single point where you need to make a decision when you're playing in single player.
The presentation is sufficient for a XBLA game, the music is ok, although a little repetitive and there is ok gameplay, but the game just lacks... a lot, and also fails to help out anyone who doesn't know how to play. But considering it's free if you download it in the next few hours, it's better than nothing.
