Lives

The player has 3 lives and when you loose 1 life the player ship is ghosted out and unable to fire but it can be moved that way you have a better chance not to be killed upon reactivation.

Enemy Movement

The enemy is spawned along 4 different paths and into a moving formation from side to side. Once all the enemy have been spawned the formation swells from the center outwards by an amount relative to their position ie smaller in the center and more on the outside.

Once they are all in the formation they randomly fly out and down on a attack path randomly chosen from 4 different paths. 

Once they have flown down the attack path they are re-spawned at the top and fly back into formation

Enemy shooting

At the beginning levels only the purple enemy fire missiles and they only do this when flying.

Game play

Once all the enemy have been killed a message with the next level appears on the screen and a fresh lot of enemies are spawned
