I made it so that enemies can only be killed by touching them, but if you touch the enemy when he is looking at you, you lose 1 HP, and if you touch when he is looking in the opposite direction, you do not lose HP, if you touch the enemy from the side, you can lose HP with some chance (if it is closer to stab in the back then 25%, and if it is closer to stab in the face then chance is 50%)U
