Finished2D shooter!

This is the final version of the 2D shooter I have made. I changed a lot and made lv 3 hard to be careful of that

I changed;, the background (including, planets, astroids, spaceships, and black holes)

I also changed the amount of enemy's per lever so it gradually got harder (kinda :)  ) and finally every enemy has changed health, speed, and weapons.
