Hi Jack :) You're right though in your points about gooma and beyond. I will retest getting the flute first vs doing gooma first when I get there though to make sure the route makes sense. I don't even really remember why doing gooma first was faster in the old movie. Either way, though, the crystal exp is going to happen. Either we up&a at the flute or we don't up&a at all, so you can count that exp in the route.
So I guess it's really just a matter of sorting out the optimal way to be 3-5-1 after the first three palaces?
and it might be possible to get the healer lady to spawn sooner than what I do in the published run, and it might be possible to get the downstab teacher guy to spawn a bit sooner too

I'm assuming they're playing on an actual NES and not emulation.
