Sorry I made my game Windows-only! In Ludum Dare 47, when I tried to build for web, it gave me nearly 200 errors in the web console, so I was a bit against HTML builds after that. I'll try again next time, I suppose...
Ok! HTML build on my game page works perfectly! You can try it now at https://itch.io/jam/mix-and-game-jam-2020/rate/822081 , just quickly! There's only 4 hours left!
