We tried something like that before. I think if you jump down to the sigil, the turrets will kill you before you reach it, at least that is what I remember. Maybe there is a fast way of jamming the turrets then using the paint?

If you turn towards the Sigil after climbing the ladder, then the gun will shoot you before you can grab the Sigil, even though it looks like you can grab it. All you have to do is run straight after climbing the ladder and you will be able to get the Sigil.

Yes, Moussmoose! My fps drops down to 16-20 after the part where you fly over to the connector and jammer with the box during the top of the tower. It remains that low until the run is completed. If you do the old strat where we skip spawning Samsara and Shephard, then it shouldn't lag.

Wow, it is still possible to make that jump! It is also possible to skip blocking the mine, and get the earlier cycle (not worth). I was able to get a time of 14.08 seconds using that jump and getting early cycle, but I probably won't go for it in a run.

I found a new strat to do B7: Big Lump of Mine by hiding around the mines using the two hexahedrons given in the puzzle. It saves about 10 seconds but it's risky. I was able to do it consistently though after a lot of practice. This is what I came up with:

Hopefully, this will inspire you guys to find other puzzles where this trick can come in handy.
