Heh, it's a very nice game.
It's very fun slicing and killing zombies, also because you can basically slice then in infinite different ways!
I liked the game from the start when you said "Somewhere in nev.... newgrounds", just like in Mandness "Somewhere in Nevada". It's a bit short, and very easy, but still fun to play.
There should be more weapons like a rocket luncher slicer or something like that, or game modes, like a hard more or a gamemode where you die with one hit, or another gamemode where zombies die with more than one cut..
Nice work. Keep it up. No bugs encounted.
