Coursera 2D Shooter project

Hey there, this is my 2D shooter project for coursera course in unity programming. Here are the three major modifications I have done:

1. Modified the UI in game: you have an health bar and a power bar showing you life and the power you have in order to activate power shields.
2. Designed other choerent levels: I have built three different levels with three different layouts and different enemies you can enounter, the more you proceed the more it gets difficult.
3. Added new powers: I added the ability to activate shields after you have killed some enemies by pressing Q, I've added destroyable walls (in level 2 there are walls with different health) and I've added hearts to recover life points you lost by being shot by the enemies.
