Mastering sword fighting is an important skill in Troll Bridge. The troll character is left handed so attacks don't come from the center. Also while the blade is extending and retracting, the character cannot move. Although later weapons such as the enchanted sword allows attacking from a distance, this only works when at full health. It is best to practice early on with the sword while the opponents are weak.
