It has potential.
This game has the potential to truly be something else, but there are a few things that need to be fixed or added.
-- As others have said, a Map function would be very helpful for knowing where the extra areas are, but you don't necessarily need that to tell the player where to go. Having the arrow that follows the storyline flash green, and the arrow that leads you to extra areas that still have loot or zombies flash red.
-- I don't care what the Author Comments say, zombies walking through walls is lack of effort on your part. Most of the time when they do so, there are no windows for them to climb through, because they're inside a 2-story house or stuck in a basement. Even if there were windows, what's the chance that zombies would think to break a window and climb through it?
-- It's strange for the character to be moving across the screen without moving a single muscle, adding walking animations would add to the quality.
-- So wait a sec, the Nurse is equipped with a badass chainsaw, and she's SLAPPING the zombies?
- Party Members
-- One person up against an army of zombies doesn't seem very realistic, does it? More characters joining the party, such as the person who is in the house with you at the start, would add to the fun of the game.
-- The clothing stats are extremely questionable, because according to this game, a Shark Suit is three times more protective than a bullet proof vest.
-- It's too easy for you to get stuck deep into the game because you got badly bruised in a fight and don't have any med kits to heal you. It would be better if you could go back to an area that auto-generates zombies, kill weak ones until you level up, and regain full health as you level up.
- Finding Loot
-- I'll be blunt: clothing, bandages, and melee weapons should be found mostly in houses, and guns and med kits should be found in abandoned shelters or on dead bodies.
-- It doesn't make sense, why are there boxes of medicine, guns, and everything else you could possibly need to kill zombies lying around randomly in crates? They should only be found in houses, or near an especially large group of dead bodies.
So yeah, I doubt you'll even bother to read the reviews, seeing as you tried to put the wall glitch off as intentional, but whatever. My opinion's out there now.
