I noticed most of the games with ratings were HTML5 games. Makes sense since it requires more effort to download an executable, unzip it, etc. and it isn't compatible on all platforms.
I didn't realize that WebGL export in Unity meant HTML5. After a bit of tinkering (need to set compression to 'gzip') I was able to get it to run properly. For those of you with Unity games, I recommend setting up this option so more people can play your game.
FYI here's my game, would appreciate any feedback :) https://itch.io/jam/n8jam/rate/1158715
