This is the main menu from where you can either start a new game or quit the game just by clicking the respective button. You can also get here by pressing Esc key from inside the game.
This is what you will see after you click New Game. Here, you need to hit the asteroid first which will then start spawning the enemies and power-ups.
Here, you can see different type of enemies in the game, one that moves towards player when near, one that moves in a zig-zag which can also have a shield, one that can avoid player laser and different default enemies that moves side to side or top to bottom.
You can also see the shield changes color with each hit it takes and after 3 hits, it disappears.
Here, you can see the homing missiles working perfectly finding the enemy and following it until it hits.
And finally there is a boss fight after Level 5 is survived. You win if you successfully defeat the boss and lose if you die before destroying the boss.
There are lots of feature to be explored and I would love it if you give it a try 2D-Space-Shooter. Enjoy.
