The concept itself is truely unique unlike any other game as far as I can think of. Combie puzzle with platforming and you get a truely fun game like this. Well done.
There should be an ability on the login screen to "remember me" so you don't have to put in the password and username everytime. This comment was recently pushed away, but it should be seen.
So its a good concept, unique and all, however I think that once the official game is out there should be seperate difficulties, and within those are the easy levels, medium, hard, etc. Also, it would be much more enjoyable with some better graphics. i know we don't see them much, but it helps.
Good game. The only thing I have to say is melee weapons could be more "accurate" and by accurate I mean when the zombie is right in front of you it should hit when it doesn't.
