I have a few things to say about this game.
First, the controls were very confusing, making it difficult to maneuver the player while playing. The aiming system was very inaccurate, and it was hard to actually aim at a zombie. The shooting was buggy, every time I pressed the spacebar, there was a delay, and sometimes wouldn't even shoot. Also, I'm not completely sure what went wrong, but I would aim at a zombie, shoot, and nothing would happen.
Other than that, the menu was amazing.
Next time could you please simplify the controls, and maybe add an option menu that allows you to change the sensitivity for the aiming and turning?
What a piece of work is a man? How noble in reason, how infinite in faculties, in form and in motion, how express and admirable how like an angel! What apprehension oh how like a god! The beauty of thee world, the paragon of animals, and yet- to me, what is this quintessence o' dust? Man delights, not me. Nor woman either, nor woman either.
