Controls: Arrow keys move, A/D=dodge (invincible frames), S=duck (avoid high attacks). J=Jab (fast, low stamina), K=Hook (heavy), U=Uppercut, Space=Cross. 1-3=difficulty.
Stamina: Attacks cost stamina. Blocking recovers stamina faster. Zero stamina = vulnerable, attacks do half damage.
Footwork: Dodge left/right (Q/E keys) for brief invincibility. Duck (S) avoids high attacks (jabs, crosses).
Knockdown: Heavy hits when HP is low can knock you down. MASH buttons to stand up! 3 knockdowns = TKO loss.
Scoring: 10 rounds × 3 min game time. Damage dealt - damage taken. Defense wins championships!
