Hey man, so I didn't get it at first (didn't read the how to play, that's my bad). Once I got it it was simple, straight to the point and fun. I admire that you didn't use any AI, really great work!
Also some feedback: try explaining a but more in-game. Example , "stand" has no correlation with "AI turn" so you gotta watch out things like that. You may know how the game works but never underestimate how clueless people can be!
