SpaceWarShooter2D

This is my modified 2D shooter game, I made a little change on the level 1 but there's a significant change on level 2 and level 3 and these two difficulties are increased significantly, and try to pass the level 2 ! 

Modifications:

1. level one's component, and I added the live and health of the player

2. level two: significantly changed on game layout; added a lot of enemies and enlarged the map.

3. level three, based on level two, I added on more enemies and fly enemies as well.
