Tap on the icons to jump and shoot.
At this zombie game you will be on the platform with zombies. Jump on platforms and shoot the zombies. Collect ammo for your weapon. If you don't have ammo you need to jump over zombies to go to the upper platforms. Do not collide with zombies or you will die. Try to kill more zombies as you can and to get higher target. Use arrow keys to move the player and space bar for shooting, or just tap on the icons on your screen.
