Simon's cat boardgame

This game is a free adaptation of the boardgame "Siam" (https://boardgamegeek.com/boardgame/20782/siam).

To win the game, be the first player to push a rock off of the board. Either animal can push a rock, but if you want to push an animal facing you, you have to be superior in numbers, e.g., you will need two animals to push one or three to push two.
