great you’ve upgraded this to work with current macOS but the old version you could play on a keybaord with two players, now if I try and play with two players it says attach a controller which I don’t have.

Can you just make it so that you can use up down left right for one player and w a d s for player two like the old version? The joy of this game is its multiplayer function 

Hi, the modern version of CMR does not support single-keyboard multiplayer (here’s why). However, if you only have one controller, the game will let Player 2 use the keyboard.
