Enjoyable, somewhat repetitive
Good game, fluid feel and some decent graphics. While the last might sound bad, alot of Flash Artists seem to think that they are expected to make the Oblivion of flash but a focus on arcade graphics really helps flash games.
It was repetitive though, quite. You meet new zombies and level up and that's it really. No buying a gun option? No guy in the backround saying "Cool Combo"? It needs more substance.
On an additional note, I seemed to be having a glitch with the soun where I could hear two peices of audio going over one another and nothing in the Audio menu could turn it off. Could you fix this bug? It's incredibly irritating after a while.
