Arcade Game - Minecraft Salvation

Originally, the main reason why I made Minecraft salvation was; unlike the other projects, due to a school exam. And in case you thought I was a PhD, I'm not, and yes, I go to school, hence, some of my projects originate with an exam or a test. The game story line is about a group of Minecraft mobs (living things that are not humans in Minecraft) which decided to destroy the Minecraft world and turn it into cardboard. The goal of the game is to kill the five mobs: Creeper, Stray, Skeleton, Warden and Ender dragon. Only then, will Minecraft world survive so that all the kids and adults in the world can play Minecraft again; actually, realistically not the adults. At the beginning of the game you can choose your favourite launcher and ball. You are then given ten shots to shoot all the non moving targets: Creeper, Stray, Skeleton and Warden and the moving target, the Ender dragon. If you don't manage to defeat them in ten shots or less you loose and Minecraft will be destroyed...
