Sorry for the delay, I was on vacation. The standards for getting a high score are pretty high I remember, you need to not really make any mistakes. If you want, can drop me a save right before you talk to Morris and I can check what the score was.

Yes, there's no way to download saves on the browser version because they're saved in the local storage in the browser and it's a bit messy. I'd try in the future to make it possible to import/export saves in WebGL.
I'll check it out and see if everyone's happy if I still reach the bad ending, thanks for the report :)
