I can see where you trying to go but needs work first off need flashlight right as you start. Because zombies attack you in the dark and you cant see them. So the little 8 bullets you have are finished after shooting 2 of the 4 that just race at you. I get you want to make it hard then give a little and make zombie fall on one shot so no biggie only 8 bullets. Again game has promise just needs some fixing up.
Thank you very much for taking your time to play my game!
The flashlight is available right from the start, by pressing the F key.
You can pull out the drawer, there's a lot more ammo there.
I should have made it more obvious that they are interactable, I made this project a very long time ago. Apologies!
