I think developing strictly for a Windows / executable build was a big mistake. In an attempt to port to Web later on I found that many of the rendering techniques we're using for certain things (decals and outlines specifically) just aren't super compatible with Web builds, at least not out of the box. We definitely over scoped for our first jam but were ultimately happy with what we were able to produce. I do think the lack of Web build availability is going to hurt us in terms of number of players willing to give it a go, but that's a lesson learned for the next time around.
Dropping a link here if you want to take a look at our submission. Cheers!

Were you using Unity 6 URP? I also had an issue with decals which were important to the game. I found out that part of the problem was that Unity 6 uses forward+ render by default (at least for URP, maybe others) and that borks the decals in webgl and causes a bunch of other issues. It barely worked at all in Firefox. Switched URP to forward rendering and set decals to screen space and now it's all good.

You nailed it! We were on Unity 6.3 LTS using URP. I played around with some settings but was ultimately just too exhausted after a long week to spend the time troubleshooting and fixing the Web support. I'll be taking a look at your game a little later this afternoon to check it out, thanks for sharing your experience and the fix you put in place!
