SystemExit()

Modifications

• I created a health power-up item and script and added a health display UI item/script to the score/high score display.
• I created a new portal asset that lets you exit to the next level and the associated script for it.
• I used the pyramid space station art asset along with a modification of the Enemy script to create a Boss enemy that you must defeat for the last level.
• I modified the enemy assets and created a new Mine enemy that is stationary and shoots in 4 diagonal directions.
• I created 3 levels:
  • In the first level, you have to flee your home system under attack and find the portal to exit.
  • In the second level, you have to make it past a blockade including mines and other enemies.
  • In the third level, you must defeat the boss space station to win the game.
