How do I drop all of the matter I have all at once? I've seen Brad doing it in the QL, but I can only manage to drop it slowly. Anyone know how?

I think you just hit both triggers at the same time

I find hitting both triggers at once like the game tells you doesn't work. Hit the right to start releasing as normal, then depress the left shortly after and it will dump everything.

i recently found the x button to be of great use as well. on an unrelated note, real life from dust

I went through the whole game neglecting the X button. Perhaps I'll have to give it attention in the challenges.
