I figured out that you can attack almost all the main bosses once before they start their speech. Got through the second level without picking the shootable fire weapon and tomorrow I'll try it with the weapon. I think the medusa boss will be faster with it. Maybe I'll upload some more video of my gameplay tomorrow also.
Looked alright. I'd like to see a bit more of the game though. I say keep TASing it, if it seems too boring after a while, just quit it. That happened when I tried TASing a few games. I realized there would be no way the runs would even get accepted. Who knows, maybe you'll find something interesting to exploit. :) EDIT: Oh, and after the first battle scene I THINK you could save a few frames by not walking directly up against the right side of the screen. Instead, walk left for a bit, then walk rightward at full speed (and get to the very edge of the screen right when it starts scrolling). I'm bad at explaining. Watch what i do in my TAS after the first battle: http://www.youtube.com/watch?v=mh1f1HJuFME But definitely keep up with this!
