Ive just found the start of it really slow. Practise jumping. Right now go here, ok now go there... and the only weapons i have so far are metal poles of one kind or another and my guy can only swing them like 3 times before he gets tired and has to back off.

So much better. Until about level 15 in everything you'll feel like a helpless Librarian caught up in the apocalypse, but eventually running and killing won't be much of an issue.
