@info-creaticode what if I scaled everything down, would that be less stress on the computer to render?

I have been working on a engine for a 3D backrooms game, only problem is, the game will crash the whole browser if i try to add anything more to it, even just adding some sounds, it just wont run, and then my browser says this page is having a problem, then the browser self destructs.
Please help, this is the somewhat stable version.

I have been working making a working 3D engine for a game I am going to make, and this is the second version. I have added, a flashlight, replaced turning manualy with turning using the camera, added straifing, emotes, and lighting stuff. I’m pretty much just making this so when I make a 3D I will have a project I can use for the movement, lights, collision etc. I plan on adding a wiget menu where you can equip items, gear, and guns, also I’m going to try to add collision. Let me know what you think. I plan on making a backrooms game, but making a 900,000,000+ square mile maze is going to take hours, does anyone have a faster way? Also I need a way to keep the 3rd person camera from going out of bounds.
Controls:
W = Walk | Q = Run | S = Walk Backwards | A/D = Straif left/right | F = flashlight | 1 - 4 = Emotes | Scroll = Zoom In/out |
