What I liked:
- The gunshots look good, and the sounds don't get boring.
- I also liked how the zombie enemies' body parts get destroyed, but they continue to attack. It's interesting.
What needs improvement:
- The models look like inflated party balloons. I recommend downloading free zombie models from Sketchfab and using them in your game. Many creators give away their 3D models for free and CC0, and you can use them even when selling your game.
- The ESC key doesn't work, so it's impossible to exit the game.
- The player note in Arabic is incomprehensible to an international audience.
