I originally posted this in the comments but then realized it was more fit for a discussion topic rather than just in the comments. Anyways, I have a suggestion. 2 suggestions, actually. Great job so far by the way. Anyways, suggestion #1. I don't know how you would do this, but... it'd be really cool if you were able to program it such that his max health was only 1, but, if he slept in a hay roll or tent, he'd gain health above his maximum. After all, sleeping gives you above maximum health, and he's /always/ sleeping. You could either do this to a maximum health stack (which he would be able to reach faster, through only a couple nights of sleeping), or just keep going higher and higher, giving him like maybe 20-30 health each night that can stack indefinitely.

2nd suggestion. Again I don't know how to do this, but because he has such low health, he either does not get a health penalty from making Telltale Hearts or Meat Effigies, or, instead of losing health, he loses sanity or hunger. It'd probably be more balanced if he lost sanity or hunger instead.
