Adding zombies to my shooting game on xcode 7 on macbook air 2015!

Imports a phone-drawn PNG zombie into Xcode, replacing alien sprites; adjusts enemies to 30×45 and spaces them across the game. Shooting works: zombies die and reappear at the top; deleting unused code fixes earlier random enemy stoppage. Planned improvements include walking animation, blockier art, blood effects, one-kill bullets, scoring, and five-zombie game-over; restart currently breaks the gun.

The project is progressing through iterative debugging, feature expansion, and increasingly specific aesthetic/gameplay goals.
