This was pretty fun! I played the full length game with 4 players, and only got a little bit bored after 10-th round...
The concept of the game is pretty good, I haven't heard of this kind of game before. And I love the Mexican imagery of the game.
Great work, but I'm giving it 3.5 stars because AI was pretty easy to beat. There should be easy/medium/hard menu to choose the opponents.
