This is a Problem with Webassembly I'll Try to fix this error
There are no shaders in the game only paritcles.
But there is a download version too.
ahh yes, i've had that before and that will cause a stutter, that can be remediated by preloading the particles as well, i saw a FireBelley video of his preloader that accounts for particles, i think, don't quote me on it, the 4.5 shader baker thing i'm thinking of doesn't do particles, i could be wrong though
