I logged in and moved between the buildings a bit.  Interface seemed ok except I had no idea what else to do.   I would have to spend some time reading the FAQ and/or wiki for the game.  Not sure when I will get to that but hopefully sometime in the next month or so.
I'm doing much of the same.  I'm playing a military medic, roaming around aimlessly as well.  I've only punched a zombie ONE time.  I used up my pistol without hitting anything.  
Ah, well... the interface is interesting.  It resembles Overkill in some ways.  Playing within a web browser is neat, too.
