To be honest, the design is cool, but the negative things of this game are the movement, in the sand you look like you're in the snow, you can't stop moving properly, and the game is very confusing sometimes, like story level 1 i shoot the target a hundred times and i had to get near it on the top left corner and shoot the center for it to work
i was looking for open world 2D zombie games, i know it's asking too much, but it's a good suggestion to add a open world, doesn't need to be realistic or too complex, just survival, you know?
