Thanks! I ran shy on time and only implemented a small amount of reactivity. There's two slightly different endings, both equally fatalistic.
If I go back to touch this up I'll definitely add the alternate route, some more reactivity throughout, and cajole my friend into giving the captain a walking and climbing animation haha. That ended up being an "oh crap, it's the morning of the deadline and I still have the placeholder stick figure asset in for the captain" decision.
