I don't know how it works on Safari, but I can imagine it's pretty bad. When I ported the game to the web, I ran into a thousand issues. I fixed a lot of them, but the game still feels awful in the browser, the diffecrent atmosphere, the weird audio balance, the lag, all of that is still there. So I wouldn't be surprised if something doesn't work at all on Safari.
For some reason, I decided not to make Linux or macOS builds this time. That was my mistake, sorry about that
