Hi! ;D

I just wanted to show my first own-made Java-Game.
Please give me some Feedback what i could add to make it better.
I know it’s not much. Just a Minigame.

Description:
2D Space Game is and oldschool-styled Shooter like Space Invaders.

The Goal is to reach 100 kills but it’s getting harder and harder to survive.
