I'm having performance issues in wasm too. I won't rate this one, as it looks like there is some work in it, and i couldn't make it justice.
Thanks for the feedback.I think I should remove the gpu particle system hanabi.bevy = { version = "0.16", features = ["webgpu"] }
bevy_hanabi = { version = "0.16", default-features = false, features = ["2d"] }
I saw this low fps on my phone, but thought: on the phone, so what.
