Was curious about this since it's similar to our jam idea, sad to see you ran into the WebGL build error :(
Do you know what caused it? If anyone else has experienced this then I'd feel a bit less despaired.
P.S: you didn't miss out on much, I only had 30 hours out of the 48 to work on it. No sound, and two levels 😂
Yeah, we sadly ran into the same issue but luckily I had come across the fix on the GMTK Discord Server. It's something about switching the compression in the Build/Player Settings from brotli compression to gzip.
I'm still happy though, managed to finish and submit a game into this jam for the first time.
