When you go to the store and buy a pet rock, a fake piece of poo, or a movie called L3GiT-Sh*theads The Movie, you shouldn't go home with your purchase expecting much fun upon your arrival. That's the kind of game Zombii Attack is. If you've done any research at all on this title (like, just reading the name should be enough) and you're still under the illusion that it might be a well-made game, then you probably only have yourself to blame.
The weird thing about obviously terrible games like this is that they are sometimes more fun than you'd expect. I figure that's part of why Cow Clicker turned into a thing for a while there. Sometimes a game can be so dumb that it actually makes you think. Sometimes a game can be so terrible that you can't help but laugh, and therefore, you'll have a not-so-terrible time while playing it.
I went into Zombii Attack hoping I'd have that kind of Cow Clicker "fun." Is the game an effective parody (intentional or unintentional) of both gaming's most overused cash cow character (the zombie) and of its most soulless game design hook (the Angry Birds-style physics launcher), or is it just a terrible time that will make you hate your mind and body?
