I almost forgot, the enemy visibility per difficulty is already hard as it is. I'd rather fight enemies that are ever more difficult to kill and defend myself from by some clueless mistake I make anyways.
I want a 3rd Spear and Katana game, but this time, a real RPG version, more player character customization, and enemies should be harder to kill and at the same time deal more damage to you if you are not blocking or stepping away backwards against them. And a more detailed RPG storyline reflecting your origins before becoming a skilled warrior among the famed legends of war.
