Defeat all 10 bosses! Move with Arrow keys or D-pad. Press X to attack, Z to block (halves next hit), Space/A for Special attack (AoE damage + heal). Watch boss telegraphs carefully: white line = charge attack (dodge sideways!), red circle = AoE blast (stay away from center!), orange glow = summoning minions. Bosses enrage at 30% HP becoming faster. Choose 1 reward after each boss. Final boss has double stats!
