WASD / arrow keys to move, use the one you prefer :) [Click] - Shoot [L] - Show line of sight Line of sight is testing to see if there is a wall between the zombie and the player, if yes the zombie will remain idle, if no the zombie will walk towards the player. The thumbnail is draggable so just drag it away at the start of the game. Tips: At the start, I suggest you first kill the first zombie then drag the thumbnail. The first zombie is standing to the right of the player (the player is at the bottom left of the level), so shoot to the right. Turning on the line of sight would also be a good idea so that you know when the zombies can see you. If they can, they will attack.
