My project is a small Godot game, but it takes forever to load, lagging or even freezing the entire browser.  On some browsers (Chrome, most notably) it freezes the browser entirely for a few minutes and then just spits out an error message and never loads at all. I've seen other people's Godot projects on here and they load quickly and smoothly, even when they're much larger and more complex games.

Compare load times: https://greatunclepixel.itch.io/findtheflag (my game) vs. https://hairic.itch.io/hectic-toys (from a streamer I've started watching).  ... this is not an attempt to advertise my game. :D

I'm obviously doing something wrong, but I'm not sure what it is, or even whether the problem is in my Godot settings or my itch.io settings.  I hope someone can help. If you need more details, let me know.
