Four-Knight

Really awesome casual strategy game for fun times with friends, my only critiques/requests: 1. Starting advantage is pretty huge with 2 or 3 players: with 2 you are always 1 closer to 4, and with 3 players, 1 player basically ends up pulled apart trying to tend to the other 2's setups, so it would be nice if there was some kind of evening factor 2. Please allow an undo button for local pvp with no bots to account for mistakes like one player using another's move by accident 3. It would be neat to play for second and third, i.e. when a player wins they stop placing pieces and the other players continue playing the same board
