That was amazing!!! You did such a good job!
I'm not an expert with expert with making WebGl builds but I've setup a few of my unity projects for WebGl. I'd be happy to try and help (no promises on me being able to get it working tho xD)
I've made a ton of WebGL builds before, but this time whenever I export it's a black screen (still sound, but no graphics). I've Googled for hours and it seems like it's a somewhat common problem, but I couldn't find a fix which worked for me. I think it might have to do with URP or the 2D lighting system?
Also, thanks for the kind words about the game :)
