I made it into a game, the game may be slightly buggy a & d to move 1 to equip Rifle 2 to equip Axe e to unequip q to aim space to stop aiming The Rifle has a 2 second cooldown and for some reason it pauses when you change weapons, it's not game breaking though
Added a boss fight after you kill 50 zombies, you need to hit the boss 7 times to win, good luck laddie!
