Wow great script, but how would I go about putting in kill able enemies?

--Edit - Also how would I put in a point collection system with onscreen display and health bar also could I make the guy climb rope and ladders?
Also is it possible to put in static items that hurt the player like fire.
and is there a drop distance that kills the player, like the holes in Mario?
I know there are loads of questions but i no nothing about scripting.
Thnx
