Something with the GPU particles in Godot causes it to get stuck like that. It happened when I was working on it in engine too.
Thank you for playing and for the comment!
exatamente a Gpu particulas tem algo contra navegadores, para navegador costumo usar a CPU particulas, elas tem um desempenho melhor em navegadores.
I did it for the lighting effect with HDR. I didn't see a way to do that with CPU particles without going into shaders
Mas ficou ótimo, parabéns
