With that said, here is my basic strategy to beat the game.
Spear weapon - Throw at enemy, you can also catch the spear from when you kill a spear warrior
Sword - You use this as your primary attack. I find that walking up to the enemy with the sword swinging is very effective.
Kick - Disables enemy so you can kill with sword.
Level 1 boss - no issues
Level 2 boss - Block spear and you are good to go.
Level 3 boss - keep kicking him until he is dead!
Level 4 boss - I play cheapâ¦kick strategy works again
