https://m.youtube.com/watch?v=GiG92Kouh7s When the in game Time show 4.93 is when i used BSCB. Skip to 1 minute 2 seconds to see the BSCB. How to do: when you see your character but the black screen isn’t fully gone thats where you want to do your inputs, might work even sooner. It is preferable to use the dagger since its faster. Pros: Allow for faster completions, consistent with pratice, decent visual cue. Cons: Timing is hard but learnable, Must start with the dagger to avoid losing time in some levels. Doesn’t work in 1-1. Discovery: idk if anyone used this before but i found it out by accident in my last WR run attempt (which probably helped the next one achieve a sub 5.)
