Pygame running speed of website(pygbag) is much slower than Local-EXE

[songyuyx]

I made a simple games by pygame, and it is running good in Local-Exe files.

after use Pygbag to build it to a web-games, the running speed is running very very slow in localhost:8000, and also in itch.io.

May I have any comments to fix the issue, thank you very much

usually the first thing to check is your display size : 1024x600 is ok enough including mobile.

incremental display also saves a lot of processing ( ie pygame.display.update() instead of flip() )

next to check is game logic, especially assets/surface handling.
