Space-Fighter

This is a school project.

All game assets are made by myself.

Goal

It's a game where you can conrol a rocket.
The goal is that none of the Aliens hit the rocket or the bottom of the screen / earth.

You can achieve that by killing the Aliens with the Laser-Gun of your Rocket.

Attention: You can't shoot and move at the same time!

The difficulty must come from somewhere^^

Also you can't shoot more than three bullets at a time.

If your bullets don't hit one of the aliens your score decreases by one.
