RPG combat & quest engine

This is just a basic engine I'm going to use for a future RPG game. It'd be good if you could give me some feedback on the combat system, is it too basic? (Note: more weapons will be added)

Controls:
Z: Attack
Space: action/pickup
Arrow keys: move
i: inventory

Also, these are not my sprites/tiles and I have taken a few codes of which if I decide to use I will give credit =)
