Impressive work. The grenade jumps were interesting, as was the descent, something I discovered by accident relatively recently. Avoiding dying on impact is hard, though I have been able to land with half-health a number of times, much like you did here. I once was able to land with full health, to my amazement - that was in fact what got me interested in attempting that jump some more, as that happened pretty early in my attempts. I originally thought you needed the Overshield to make that jump, but on a save I had without an Overshield I decided to attempt the jump a few times just for fun, and much to my surprise, I realized you can bounce off the little edge onto the other part, with varying success - it's hard, though, and requires some practice. Still, very handy!
