The code consists of engine and business logic code, with the engine taking up more space. Engine optimization is simple - remove unused modules, and avoid using modules that take up large space if possible.
usiness logic code generally can't be modified, but 95% of developers overlook an important point: setting.js. The size of setting.js is determined by the number of files in the resources folder. Resources not loaded by code should definitely be placed outside the resources module.
elow are the engine modules and their descriptions for reference:

JPG format images are smaller than PNG; after exporting art, use TinyPNG tool for compression; image resolution of 960x540 is sufficient, consider reducing resolution if higher
Use 9-slice images instead of full images when possible to greatly reduce image resolution and save resources
Image clarity: Adjust quantization coefficients for PNG images to reduce key information clarity without changing resolution, achieving resource savings
Image pixel format: Use ARGB4444 format for color images
After sprite atlas packing, organize and adjust empty spaces to reduce whitespace
Minimize frame animations, or replace them with skeletal animations to save resources
Recommend using MP3, OGG formats for audio effects
Stereo audio is twice the size of mono; can reduce size by adjusting sampling rate to 44100 samples per second using compression software or video encoding tools
Background music is usually larger, prioritize optimizing background music size
Use bitmap fonts for special effect text when possible - a few letters + images are much smaller than a complete font library and perform better
Use system font libraries when possible
Use fontmin tool to compress font libraries by removing unused characters to reduce size
Bitmap fonts are faster but use more memory; vector fonts are slower but use less memory
