Something wrong with the build size?

My build size is too large, i check in the console editor log file and there is a big percentage that don’t know where is.

How can i do to make my game weight light?

Sorry for my bad english, look the photo and will be easer to undestand: Cattura hosted at ImgBB — ImgBB

Ps. The smartphone sign 77.45 mb when is installed, why?

Textures and Audio is the heaviest things, in the inspector, you can reduce its quality and the size. And 4 Mb for dll

You can also use diferent ways to compress the game when building.

Good luck.

If getting error similar to:

The games menu will work but when i click play to load the next scene i get an error stating: WebGL: RuntimeError: memory access out of bounds.
