I think my first was 64% with 3:57... Pretty crappy..
Anyhow, I am trying for a speed run right now..
I am at 1:02 with 180 missiles and 10 super missiles going into Tourian... Not THAT great, but ok..
Some problems that gave me trouble were some of the expansion packs that required really precise spinesharking (an example would be the collapsable block missile)
If all goes correctly, I may be able to hit the 1:30-1:40 mark.. Which is not TOO bad for my first time through..
im doing a hard 100% run and im at the last save missing the last e-tank and i have about 1:30.. so i'll easily beat the 2 hour limit. this was my first hard mode guy too, i'll be happy to get that ending! after that, hard 15%.
