NEW UPDATE:
It's been 1 week since I posted anything on this subject but the development of the game is progressing very well.
Enemies can now be shot and killed, I made the zombies have multiple phases.
- Phase 1: Walking
- Phase 2: Running
- Phase 3: Crawling
And the zombies can also attack the player when in range, and they can deal damage to the player.
I have also created a desert level, and I plan to create 3 more levels and a tutorial before uploading the game.
I'll be uploading a demo video shortly after tweaking all these added features and polishing them.
Peace.
