Play the role of Gerba who is ready to take the revenge from the assassins who have poisoned the emperor. Your mission is to fight through the enemies and collect the six magic reagents to heal the emperor. Use the up key to jump. The longer you hold the up key, the higher will be your jump. You can also make a double jump while you are in the air. Try to avoid the incoming arrows and bombs thrown by your enemies. Use the left arrow key to swing your sword and the right to fire bombs towards the enemy. Time your jumps perfectly so that you may not fall from the platform.
