That game is fun, but it didn't help me deal with real zombies.
Dear Game Developer,
I know you're probably not checking your email considering it's the zombie apocalypse and all, but I still felt the need to express my concern. YOUR GAME IS A LIE!
Case in point: the tulips I planted have done NOTHING to keep the zombies out of my yard. And they marched right over the cacti as if they were no big thing. The venus fly traps? Absolutely ineffectual for dealing with the undead. Sunflowers? Don't get me started on the sunflowers! Seriously, if I was that tall and had that prickly of a face, I'd be knocking down zombies left and right. But I guess these ones aren't into that sort of thing. Figures!
I hope you're happy with yourself, game developer. Now, if you'll excuse me, I'm going to try plan B - throwing birds at them.
