So, I had seen a few runs by thinkstheclown on youtube, and thought that I could lower the time a bunch by going for an alternate ending.
here's my first recorded attempt: youtube#com/watch?v=xzgvtceM05o
def not perfect, but I'm happy with the sub-hour time. notably short ~30 charons for the hopper steak near the end which lets you sneak past the big psi bug in the caves.
