This is a variation of chess where all the pieces are knights. As you don't have a king, the point is to capture all your opponents knights before they do yours. For those who don't know how the knight piece moves in the game of chess, it works like this. You can move once horizontally, and once vertically. one of those moves is 2 squares, and one is 1 square. For example, you can move 2 squares left, and one up. Or, 2 up, and 1 right. Since all pieces are the same value, the strategy is to align your pieces in such a way that they support each other.
I worked a really long time on this game, so love-it's would be appreciated. Also, if you don't have anyone to play with, post a move in the comments, and maybe it will be followed up by another by somebody else's! (EX: 1a to 2c). Have fun! Also, if this is too laggy for you, try running it on http://phosphorus.github.io/ which will run it 10 times as fast.
