Swordfighting Videogame with Two Modes

I propose a videogame with two modes. Mode 1 is played in a 3rd-person or 1st-person perspective (I think 1st-person would be more satisfying.) On your turn, you swing your sword toward the enemy's body. The motion of the sword can be precisely controlled, as can the hit location; part of the game skill is hitting a "juicy" place on your enemy.

Mode 2 begins as your sword impacts the enemy. The game speed slows down, and a picture-in-picture appears, showing a magnified view of the part of the enemy that you hit. You guide the sword blade through the enemy body part, with the overall direction of your blade determined by the angle of your sword stroke and other such factors. Your time is limited by the size of the body part because your blade is passing through them (perhaps it might be possible for the blade to get stuck, ending your Mode 2 turn early.) You're trying to do something: either deal damage to the interior of the body part by destroying the "chunks" inside, or navigating the torturous path between the chunks in order to sever the body part. Dealing damage is easier, but it only weakens the limb instead of severing it.

Different parts of the body could present different obstacles, or special unique points. There might be a special "bisect" move available if you swing your sword at the top of the enemy's head and successfully navigate their whole body; hitting the heart or stomach or intestines might do something special, if those are even modeled at all; etc.
