No-one else has mentioned so I'll put this here; I got the following error message after installing the game on the itch.io app:
Unable to parse Build/OthalaBuild.framework.js.br! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug.
I'm just using the app so I don't know that I can do anything about this, apologies.
