Installed this game with the itch app and got the following error:
Unable to parse Build/LudumDare50.framework.js.gz! 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: gzip" present. Check browser Console and Devtools Network tab to debug.
Had this a few times with games that were tested on the web but not with the itch app... something to do with the compile stage maybe? (Never tried to build a Unity? app)
