1 key is to swing, and the zero key is to pitch. 1 STRIKE = game over pitcher wins. ( switch sides who ever was batter loses.) unless the current pitcher who through the strike that made the game end also loses, then you play again till someone wins. 10 HITS = game over win for who ever was the batter. If you care rock paper sciccors to decide who goes first. Z = DINGERS!!! FOR BATTER. M = IMANGINE MISSING!!! FOR PITCHER. (TWO PLAYER.) COLLAB W/JulianJimMichael
