Really cool! I almost reached the end on my first run, but it hung a few hundred km away during Event - "The Exposure." It wanted me to press right for Next and it just stopped responding to all keypresses. Playing here on itch.
Lots of folks have hit that scenario, including someone on a twitch stream today that hit it right at the end of the game like you did - no one else had the game freeze at that point. I will add a small note to the ame page about potential conflicts with browser, but I'm not an emulator writer so I don't know that I can diagnose.
