Sorry for going on about this :D
When I started your game again I see that there are no shadows, also no glow I think. I tested running our game with compatibility pipeline, which is what is used for webgl build. It says shadows, glow and SDFGI are not supported. Anti-aliasing is also not supported. But you made a game that is playable in browser, that is worth a lot too, even without those features. They fixed the transparency bug I ran into with particle systems at least, so your fire looks cool.
