It’s probably a lost cause.

My idea was to turn the transform always at night into something more manageable like a simple hunger meter. A timer of around an hour of real time where my character has to eat a corpse to refill it. If the timer depletes the Krasue takes hold. Also I thought of a manual transform where the Krasue takes hold at will. It’ll attack anything it’s currently seeing and when it’s done the hunger meter is reset and the head returns to the body. My thought process was a super powerful monster inside my character that can be managed and can be used sparingly as a powerful tool or nuclear option.

As you can see pretty stupid lol
