I'm pro at this!
Pro Tip: Hold the A key and approach an enemy. If you're seriously worried about the occasional hits you'll get from ranged enemies block one of their attacks then proceed while holding A, you don't really need to block though as your hp will refill faster than your opponents can damage you in most cases. For fun, occasionally use the special attack. Don't worry about opponents attacking, since the attacks apparently run off of a hittest for the entire MC allowing you to attack the ogre's maces with your sword and still kill them. Ignore the S button for any purpose other than taunting the poor A.I. who can do nothing against your held A key.
To the author: This was by no means a bad game, but the gameplay is rather simple. You should put some AS in place to prevent the attack happening over and over when the player holds the key. Also you should use hitboxes or something so that enemies (and the player) take damage when their bodies are attacked rather than their weapons. Other than that, this game is pretty good at what the aim was, but I think you should have tested it out a bit more and tried to counter programming weak spots like that.
