2D alien shooter!

This is my 2D shooter project.

Modifications:

1. Added 3 levels. They are uniqe on there own
   1. 1 level: you have to escape from meteors, and enemy is on the way.
   2. 2 level: you are frozen and from 4 direction enemy is coming to you.
   3. 3 level: final boss level. you have to defeat the final alien.
   4. You have to do different things to finish the levels.
2. New enemy: alien boss. If he catches you, then you lose. Shoots big fast lasers. His Health is on the UI. Mini meteors damiging it. And he can eat other aliens.
3. Power up on level 3. If you pick it up you become faster.
4. On level 1 if the aliens collide to the wall they change direction. And if the meteor wall hits you its game over.
