Use WASD or arrow keys to move. There are 4 different types of Zombies: Green, Yellow, Red, or Blue. Green gives 5 points after you kill it, Yellow gives 10 points, Red gives 15 points, and Blue gives 20. Click or Space key to shoot. If you run out of bullets, click R to reload. Click keys 1,2,3,4 to switch guns. At around 500 points there will be a huge burst of zombies. I recommend saving some of your bombs for it. Press key 5 to release bombs. You have limited bombs (15) but I am going to add a shop. As for 2nd September, 2022, I have added 3 powerups, and starting on shop.
Done!
