Slow loading in browser mobile

Hello I made a game in C3 and I export it in HTML5, it works very well in the browser of a computer, but when running it in a smartphone browser loads too slow.

What should I do to make the game optimal in mobile?

Pay close attention to memory. On a 4-year-old iPad, I like to keep memory usage down below 130 MB. On the same project, I can use 1 GB of memory without loading problems on my laptop.
