I don't like the fact that you get loads of unlimited items... To be honest when crafting comes and items need to be made and not just spawned from the items menu , then it will be better. ( loads of things are infinite in the menu) also zombies die in 2 or 3 hits from a sword witch is pretty poor. Not sure how many times it takes on the computer version but I think that's too low. Also we need pigs and/or pork so you can regenerate health manually without it doing it automatically.
The unlimited items is temporary so that won't be an issue much longer, and I'm pretty sure the zombies die in 2-3 hits with the iron sword on the computer so it's not all that inaccurate on Pocket Edition. You're right about it being too easy though, the sword can hit them from what, three or four times as far away than it can on the PC? So they have no chance to hit you unless they take you by surprise. Also the lack of beds is saddening.. Still. It'll get better, just gotta wait..
