hate to post in a 5 1/2 old month thread in a way, but somewhat out of boredom after watching the apparant frozen-progress tas of megafrost's, since he was up to sector 5 and it finished, i thought i'd play around a little.

first is an impossible to do realtime sequence break that's probably slower than coming back later and getting it, not to mention useless. <-- turns out you can do it on a cart, but using a different method that's slower. oh well, almost thought i had something there :P
the other two are the normal and an alternate route which could be faster for getting the ice missile upgrade.
I was almost contemplating making a tas of this game when i saw megafrosts run. pretty much made me go 'uh, no. on second thought, i'll pass', given how precise and awesome and stuff it was.
