Assets Directory
The assets directory is the core place for any content the game needs to load at runtime. When the game is packaged, this will likely be a .zip file that the game automatically extracts, but either way, the idea will remain the same.
Most of the folders in assets can be named anything, and files can be anywhere, with the exception of a few folders that the game expects to be named appropriately.
