My iOS game on xcode on macbook air - development update

Updated zombie graphics with walking animations; zombies now die when reaching the tank, while reaching screen bottom triggers game over. Restart mostly works but sometimes delays game-over; an invisible collision image follows the tank, making run-over kills more logical. Plans include more zombies, faster variants, escalating waves, timed power-ups, traps, destructible obstacles, sound, and custom death animations.

The project is evolving from basic mechanics toward ambitious self-produced gameplay despite bugs and limited RAM.
