Just tried to install and run from the itch desktop app, and got the error "Unable to parse Build/13th Incremental Hunting Fix.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."
That said, itch.io has been a bit buggy the last couple of days, so I'm not entirely sure if it's the game, or just itch again.
