Heal Pill - That's what the apples are for. I get the feeling this is supposed to be a 'gritty' game (by porn standards) emulating harsh prison life where conveniences are few. You'll want to play a more standard RPG if you want easy access to healing and the like.
Expanded Weapons - Again, you're in a Maximum Security Prison. No way in hell are the guards letting inmates walk around with any large and obvious equipment like fire axes, shields, or any projectile weaponry. I -can- however, see much smaller and concealable weapons like tasers, switchblades, brass knuckles, and smoke bombs being added.
Gifting/Smuggling - Increasing affection with NPCs by gifting them hard-to-get stuff that they want is something I do agree with. Alternatively it can become a new source of income by selling it to them and letting the player take on the role of a prisonyard black market dealer.
