This is Alien Attack a modification of 2D Shooter Project

Modifcations:

1. Added 3 levels in total with varying difficulty. There are more enemies with more health and abilities (fast shooting and more health).

2.  Replaced the game background, and game music (spent a lot of time on this).

3. Changed the entire UI with a different font and added instructions that make the game have an objective. 

Further Modification that I tried but didn't work:

1. Having earth behind the asteroid layer. The asteroid layer breaks and you have to protect earth before the aliens destroy it.

2. Making custom models using Photoshop.
