2D Shooter (kaalucard)

Thank you for playing my simple demo!

These are my updates:

- Adding tiled backgrounds to level 2 and level 3. It makes a huge difference compared to copying and pasting an image file. 

- Updated code in Heath.cs instantiating the text UI to show how many lives the player had left.

- Added code to the game manager script to let the player know how many enemies needed to be eliminated to pass to the next level.

- Updated UI background.

If you have any questions on how to do any of these things, ask me in the comment and I'll be more than happy to help!
