Lore update

Since there's actual lore with Haachama/Haato, I made some minor cosmetic updates.

Updates

• Haachama is now headless to match lore.
• Difficulty has been reduced. You don't need a whole bar to outrun Haachama.
• Escape section modified to make it easier/ scarier.

I've been toying around with a possible new game mode involving finding her head.
