Updated WIP video. As best I can tell the game is now playable, and I've submitted a pull request. There's some ambiguity there since some of the deaths seem woefully unfair with razor-thin timing window, but I'm not sure how much of that is because it's 6:30 in the morning on a Saturday and I haven't slept more than a few hours since Thursday, how much of it is me just plain sucking at non-stop "quick time events", and if any of it is down to bugs.
More info in the video description.
Note that as I'm posting this, YouTube hasn't finished the HD processing yet, so the quality of the YT video itself might be a bit crap for an hour or two.
