3D FPS

Description-

1. Audio Mixer Added in Settings Menu, to allow players to change Volume levels as they please

2. A special power-up was added that gives unlimited ammo for a brief period of 10 seconds.

3. Created a new level, I had planned to create three levels, but it simply was taking too long, so I had to scrap the other two. I apologize for this below-par modification.

Also. for some reason I am unable to select the "This file will play in browser" for WebGL, I have built the game several times, but the option simply does not appear, I have attached a screenshot of it, as well a screenshot of the WebGL build running on my PC while I was testing it. I am unaware as to why this has happened.
