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.

So boxes act as a barrier between you and mines, huh. Great find! Fun to watch, too.

Excellent find! I've been trying to find more applications since I routed Egyptian Arcade, and it's actually not as common as I first thought it would be.

This is a great one, though. I will keep looking as well.

Pretty cool use of the boxes. Btw you can use only one box : you can actually make the jump between the box on the interruptor and the ledge. Kinda tricky, absolutely not worth it, but it's possible :p Unless it's been patched.. Anyway, good thinking there.

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.

The only other puzzles I see this exploit working in are the A Star puzzles, mainly Nerve Wrecker, and to optimize floor 5 in the tower.

I think you can grab both the cube and the jammer without jamming the mine on floor 5 if youre fast, i dont think you need to use this method.

You can grab both indeed.
