OMG....hanage, the world record holder, has just learned the stage 4 wall glitch!! This has never been done in a speedrun afaik and is only present on the TAS run (because the timing is ludicrous--I've tried!). He says he can do it 50% of the time, which I would kill for.. Damn trick has gotta save like, at least 15 seconds.
He was in my stream for a while last night giving me tips. Finally learned how to whip cancel (press down between whips and you can do them faster), which is pretty much only useful on Sir Grakul, but it'll still save me a few seconds. Also, apparently I showed him a damage boost on the spider in stage 2 from the TAS run that he's never tried, so that should help him shave off a few seconds..
Let me know if anyone has any questions about optimizing their speedrush of this game. I'm learning a lot and am more than happy to explain some of the tricks I do on my runs if there's some technique or timing you're not getting. Did that for quite a while with a regular on my stream last night doing save state practice and he even helped me make a few improvements. Sub 40 is going down!
