This is a greeat game. I have an idea though for levels. Since it's a minecraft fable, you should add a so called Aether level with pre-levels, so once you get the Ender Dragon egg you can have a pre-level like making a hatchery to hatch the ender dragon as your pet. Then you can fly on the enderdragon to the aether and finish the game.
Idea: Zombies shouldn't just drop dead (Implying two things) Since we have acid, limbs would break down into nothing one by one until either the acid or the limbs/body is gone. But zombies shouldn't die just because a fire (Zombies are fairly immune to some stuff) and they shouldn't die because of a shot to the body, it'll just make them fall. So the only way they should die is by acid (when the body is completely gone) fire (Same applies as acid) Lasers, guns (To the head) and explosion and other things.
Also another thing to Dragonfire's idea make fog (Water cycle?) so that when smoke comes in it become smog. It shouldn't kill but when lots are poured in water it should come out as acid.
