Use arrow keys and 'z' to choose. 'x' to go back. I recommend choosing plural -> On Santa Revenge -> Play (if you have saved replays you could choose to watch them here now) -> Xmass tree. After the game ends the 1'st option is to save the replay, 2'nd is to choose another game, 3'rd is to replay the level. When playing use arrow keys to move, z to shoot, x to bomb, and shift to slow move/focus. It's also written in "anotherREADME.txt". Hope that helps.
