Astro Strike

This is my 2D Astro Strike game.

Modifications:

1) I added an enemy spawner in every level and added black holes, planets, and asteroids in Back Ground.

2) I added a Score resetter script in all levels and "Space .png" to the background on the menu page.

3) I added instructions for controlling the game and changed the game name!
